PhD positions in Astronomy - how it works

The astronomy group offers PhDs in the areas of extragalactic astronomy, observational and theoretical cosmology, and machine learning for astronomical data. We have 10 academic members of staff that are all offering PhD projects for the 2019/2020 entrance year. We typically have between 2-3 funded places per year. The funding comes from UKRI STFC ( terms and conditions). We also encourage applications for the Vice-Chancellor EU and International Scholarships.  

A list of all the PhD projects we currently offer can be found on the  Astronomy webpages. Some projects only have one supervisor named, but all students will be appointed two supervisors if they take on the project. 

We run our postgraduate admissions a little different to the rest of the School. We gather applications until the end of January and then we invite the top candidates to a half-day visit and interview. During the interview day we advertise all the PhD projects we have on offer. We will then offer STFC-funded positions to the best candidates. The candidates then can choose their PhD project from the list we advertise. Therefore our studentships are not tied to a particular project. 

The process for VC scholarships is different, as we have to tie the scholarship to a particular project. Students should approach any supervisor mentioned in the project list if they are interested in pursuing the VC scholarships for EU or international students. 


PhD positions in Particle Cosmology/Nottingham Centre of Gravity 

The Particle Cosmology group offers PhDs in a range of topics related to the cosmology of the early and late universe. We have 9 academic members of staff, all of whom are also affiliated with Nottingham Centre of Gravity  We typically have between 2-3 funded places per year. The funding comes from UKRI STFC (terms and conditions). We also encourage applications for the Vice-Chancellor EU and International Scholarships, when they are available. 

A list of all the PhD projects are expected to appear on the particles webpages some time in November, although these should just be taken as a rough guide.  We encourage you to talk to individual members of staff about their plans for PhD supervision. 

We gather applications until the end of January and then we invite the top candidates to a half-day visit and interview, or carry out interviews online, as appropriate.  We then assign the successful applicants to the supervisor that best fits their interests, with a proposed source of funding.

 


Bell Burnell Scholarships (internal deadline: Nov 30 2022)

Each year the Institute of Physics offers PhD scholarships to underrepresented  groups, through the Bell Burnell Graduate Scholarship Fund. The school can support one application each year, and as result, we carry out an internal selection process in early December. If you are eligible for the scheme and interested in applying, you should submit your PhD application early, well in advance of the internal deadline of November 30.  You should make your interest in the Bell Burnell scholarship clear on your application, and communicate this directly to the potential supervisor and/or the person in charge of PhD admission for the group you are interested in joining. 


PhD positions in experimental Quantum Optics (Error Proof Bell-State Analyser)

Midlands Ultracold Atoms Research Centre – Muarc Nottingham, UK

Efficient atom-photon interfaces are a central part for quantum computers, fibre networks or miniaturised quantum sensors. This exciting project creates an interface based on a cloud of cold atoms trapped in a micrometre sized intersection in an optical single mode fibre. A fibre cavity can be added to this system and the strong coupling regime reached. We will also expand this concept to two dimensions (photonic waveguide chips), which currently have been very successful for photonic structures, such as interferometers and photonic quantum simulators, but so far have not included atoms. The PhD project will build on our existing experiment, where we are currently trapping a cold cloud of caesium atoms with a temperature of 100 µK in a 30 µm hole.

The project is part of a European collaboration including theoretical, experimental and photonic engineering partners from Vienna, Berlin, Rostock, Odense. The PhD student will benefit from the local research team (experiment and theory) and regular international consortia meetings.

The PhD program at the University of Nottingham offers postgraduate courses (Midlands Physics Alliance Graduate School, mpags) as well as summer schools and workshops. Benefits include a taxfree PhD stipend (currently 14553£ /year), paid tuition fees for EU/UK students and a travel grant.

We welcome applications from highly motivated students with a strong background in quantum physics.

Application: Please contact Dr. Lucia Hackermueller lucia.hackermuller@nottingham.ac.uk and send a CV and a motivation letter.


 

PhD project title: Critical dynamics in frustrated magnets and spin liquids

Supervisor: Dr Stephen Powell

Physical systems are described as frustrated when different interactions are in competition, hindering the formation of a simple ordered state. Instead, large fluctuations persist even at very low temperatures, allowing for the emergence of  so-called spin liquids, which exhibit exotic phenomena including fractionalization and topological order. This project will aim to address fundamental questions about dynamics in frustrated systems, including classical and quantum spin liquids, and apply this understanding to magnetic materials such as the spin ice compounds.

The work will involve a combination of computational and analytical studies of equilibrium and dynamical properties in effective models of frustrated magnets. Various topics are possible depending on student interest, including monopole dynamics in spin ice, anomalous slow relaxation in constrained quantum systems, and effective open quantum dynamics.


PhD project title: Computer simulation and optimisation of multilayer quantum structures

Supervisor: Prof. Mark Fromhold

The project will involve the design, optimisation, and analysis of multilayer quantum and electromagnetic structures comprising a range of materials and functionalised devices to be made and investigated by our colleagues in the School of Physics and Astronomy and within the Nottingham Centre for Additive Manufacturing, Faculty of Engineering.

The initial focus will be on understanding the interfaces, and the transport of charge carriers and heat, between the layers in the presence of high magnetic fields. This will provide the advances required to design, fabricate and understand multilayers with layer thicknesses of just a few monolayers, which act individually as quasi-2D materials and, collectively, like superlattices that are small enough to exhibit quantum-mechanical electrical, optical, and transport properties.

By depositing materials such as carbon, boron, and nitrogen, which are known to form truly 2D materials like graphene, the project will also seek to develop nm-scale multilayer devices producible by additive manufacturing. Additive manufacturing capabilities in the Faculty of Engineering will be used to make the functional structures, such as connections and mechanical supports, required to integrate 2D materials with other devices, thereby opening a route to both new fundamental physics and engineering applications. In this part of the project, the student(s) will work with an interdisciplinary team of scientists and engineers funded by our new £6m EPSRC-funded Programme Grant “Enabling Next-generation Additive Manufacturing”.


Project title:Graphene-based atom chips: a high-performance platform for cold-atom quantum technologies

Supervisor: Prof. Mark Fromhold

The project will develop graphene atom chips that reduce (by orders of magnitude) the atom loss rate and spatial scale of the atom trapping potential, as required for portable chip-based quantum sensors. The chips will enable the creation and manipulation of atomic Bose-Einstein condensates with less stringent vacuum pressure requirements than present devices, thus assisting the scalable industry manufacture of chip-based quantum sensors and clocks.

Atom chips use current-carrying microfabricated wires to create a magnetic field and thereby control nearby ultracold atoms. They exhibit robust room-temperature operation and are key components of cold-atom-based quantum sensor/clock technologies1. Existing chips use metallic conductors on bulk substrates. High spatio-temporal noise in the wires, and the large Casimir-Polder attraction of atoms to the substrate, makes the atom clouds fragment and deplete rapidly unless they are held within 5 µm from the chip. This limits miniaturisation of the chips, the potential landscapes that they produce, and prevents coherent quantum coupling of electrons in the atoms to those in the chips1.

This project aims to transform atom-chip performance by exploiting conductors within two-dimensional electron gases in graphene and other 2D materials. Our recent work indicates that these structures will reduce the atom-surface separation and power consumption of the chip by 2 and 5 orders of magnitude respectively and increase the atom cloud’s lifetime by 4 orders of magnitude – to minutes – compared with metallic conductors.

So far, our work has focused on graphene/boron nitride structures, which are promising for transistors and high-frequency electronics2. Using similar structures for atom chips opens the possibility of dual applications in electronic and cold-atom quantum devices. We now need to develop graphene atom-chip demonstrators, based on established materials such as SiC, to demonstrate the power of two-dimensional materials as a platform for quantum sensors and clocks. Existing SiC-based graphene Hall bars3, developed for quantum resistance metrology, look ideal for proof-of-principle studies and subsequent optimisation. The project will develop atom chips based on graphene and other 2D material multilayers by:

  1. Calculating atom trap profiles and lifetimes for existing graphene Hall bars, taking into account spatial imperfections and atom loss due to Johnson noise, using Green function models to relate the noise characteristics to the electromagnetic reflection coefficients of the multilayers, tunnelling and 3-body processes.
  2. Undertaking detailed analysis of experiments on existing SiC-based Hall bars: both their electrical properties and performance as an atom chip trap.
  3. Simulating the dynamics of trapped atom clouds using Stochastic Projected Gross-Pitaevskii models.
  4. Designing better samples containing multiple 2D layers to enhance functionality.
  5. Undertaking theoretical studies of experiments to be performed on these improved samples by collaborators in Germany.

PhD project title: Quantum-enabled Magnetic Induction Tomography for Healthcare and Geophysical Survey

Supervisor: Prof. Mark Fromhold

The project will involve the design and optimisation of a quantum-enabled portable Magnetic Inductance Tomography (MIT) sensor system for biomedical imaging, including cardiac monitoring, and to map ground conductivity with greater resolution, sensitivity, and penetration than classical instruments, thus enhancing geological/geophysical surveys.

In MIT, alternating current is sent through an array of conductor networks that induce eddy currents in the ground. Highly sensitivity magnetometers are used to detect the magnetic field produced by the eddy currents. The recorded data, i.e., measurements of the in-phase and out-of-phase magnetic field, are converted into information about the ground conductivity and magnetic susceptibility and further, via petrophysical relationships, into geological and geotechnical parameters.

The project will involve the design and integration of four main components and sub-systems:

  • A new, recently patented, electromagnetic excitation coil geometry uses multiple complementary wire geometries to extract greater spatial information than existing excitation coils.
  • Highly-sensitive optically pumped magnetometers for detection of the eddy currents.
  • Optimised layout (also patented) of the sensors, chosen to facilitate the matrix inversion required to reconstruct the conductivity profiles (biomedical or underground) from the magnetic field measurements.
  • Software/modelling for converting the measured magnetic field into useful medical and geological imaging information.

The student(s) may choose to consider all four of these topics, and transfer techniques between them, or specialise in one of them as the project proceeds. Depending on the interest of the student, the project may focus on fundamental topics or involve collaboration with industry and British Geological Survey, Keyworth, Nottingham


PhD project title: Computer simulation to optimise the development and deployment of quantum sensors in healthcare and geophysical survey

Supervised by Prof. Mark Fromhold

Computer modelling and optimisation is crucial for the development and deployment of new high-technology devices, prototypes and products. It is particularly important for accelerating the production and early adoption of quantum sensors for two reasons. Firstly, making the sensors will require the miniaturisation, integration, and power reduction of many supply-chain components, including atom sources and traps, lasers and optical devices, and ultra-high vacuum systems. Secondly, in order to build markets for the sensors, the advantages that they offer, and the best way to use them, need to be determined and quantified.

This project will involve the development of analytical methods and computer simulation software, including inverse and optimisation techniques, Green function analysis of electromagnetic fields, and Multiphysics modelling using COMSOL packages, to overcome four challenges in the development of real-world quantum technologies:

  • The development of miniature, integrated, low-power quantum sensor components suitable for scalable manufacture
  • Using inverse methods to understand how best to deploy quantum sensors of gravity for underground mapping
  • Quantifying the benefits of using thermal atom sensors in Magnetoencephalography (MEG) systems and designing components for such systems
  • Designing state-of-the-art magnetic shielding and excitation systems for applications in healthcare and geophysical survey (with the Sir Peter Mansfield Imaging Centre and the University of Birmingham)

The student(s) may choose to consider all four of these topics, and transfer techniques between them, or specialise in one of them as the project proceeds. Depending on the interest of the student, the project may focus on fundamental topics or involve collaboration with industry.


PhD project title: Modelling Next-generation Magneto-Optical Traps for Quantum Technologies

Supervisor: Prof. Mark Fromhold

Magneto-optical traps (MOTs) are fridges that use laser light and magnetic fields to cool atoms to within a millionth of a degree of absolute zero. They are a core component of cold-atom quantum technologies including clocks, field and force sensors. There is great current interest in miniaturising and integrating the components of these systems and in making them more suitable for scalable manufacture – for example by Additive Manufacturing (3D printing).

The project will involve the development of realistic MOT simulation software, based on both analytical and numerical methods, which includes the effects of the laser beams, optical elements such as diffraction gratings for grating MOTs, magnetic fields and the systems that generate and shield them, and the dynamics of atoms being trapped.

This modelling capability will be used to optimise the performance of MOTs for a range of quantum technology applications. Specifically, it will involve:

  • Making detailed calculations of the magnetic field profile and laser force for given trapping system and beam geometries and using a stochastic differential equation to simulate the motion of atoms within the MOT above the Doppler temperature. The model will include key physical details including multi-level atoms, diffusive effects, laser forces and Stark forces, loading of atoms from the edges of the target volume and losses due to collisions with the background gas. The model will also incorporate a method for removing trapped atoms from the simulation, so maximising computational power.
  • The model will need to be fully flexible so that it can be tailored for different atomic species and unusual laser/trapping geometries, for example those use in the Southampton micro and field-free “Magic” MOTs. It will be used to design next-generation cold-atom sources optimised for specific quantum sensing and timing applications.

Depending on the interest of the student(s), the project may focus on fundamental topics or involve collaboration with industry.


PhD project area: Atomic magnetometer and field vector camera

Supervisor: Dr Thomas Fernholz, Associate Professor
thomas.fernholz@nottingham.ac.uk

The Cold Atoms group at the University of Nottingham is part of the Quantum Technology Hub for Sensors and Metrology [1, 2]. We contribute to the development of deployable practical devices and particularly focus on atom chip technology.

One of our current aims is the realization of an atomic magnetometer and field vector camera that is capable of obtaining full vector information of a magnetic field distribution averaged over a thin volume, thus obtaining an image. With our first experiment in this direction, we are already able to measure tiny magnetic fields of only 100 Femtotesla [3]. This is sufficient to detect fields from the human heart-beat.

Examples of the research and development questions that need addressing include:

  • What is the interplay between sensitivity, spatial resolution, and temporal bandwidth?
  • What is the quantum limit for the signal to noise ratio?
  • What are the ideal materials for best performance?
  • Can we build compact devices?
  • Can we image bio-magnetic signals from the heart and the brain?

PhD project area: Quantum sensing with matter wave interferometers

Supervisor: Dr Thomas Fernholz, Associate Professor  thomas.fernholz@nottingham.ac.uk

The Cold Atoms Group at the University of Nottingham is part of the Quantum Technology Hub for Sensors and Metrology [1, 2]. We contribute to the development of deployable practical devices and particularly focus on atom chip technology. One of our aims is the realization of an atomic rotation sensor that measures rotation using the Sagnac effect [3]. In contrast to recent successful approaches that achieve impressive sensitivities using free-falling atoms [4], we confine atoms to magnetic guides and traps. This holds promise to miniaturize such interferometers, because it overcomes the need for large apparatus size imposed by the time atoms spend in free-fall.

Following our recent proposal [5, 6], we investigate methods to operate a Sagnac interferometer effectively like an atomic clock that uses trapped thermal atoms.

Examples of the research and development questions that need addressing include atom chip design, incorporating detailed analysis of atom trapping and guiding methods, optimal atomic state preparation and detection, methods to increase of interferometer area for better sensitivity and faster atom transport for higher sensor bandwidth, development of portable laser, electronics, and vacuum technology, studies on coherence properties and cross-sensitivities, and hybrid schemes involving classical sensors. Reaching the highest interferometer performance will require excellent control over a range of technical noise sources to ultimately tackling the limits imposed by quantum noise of interfering atoms and probe light. Relevant to this regime is our parallel interest in quantum light-matter interaction, which allows for the suppression of quantum noise beyond its standard limit [7].

The facilities available for this research area include two experimental ultra-cold atom setups with a wide range of supporting laboratory equipment. Access to clean-room and micro-fabrication facilities enables in-house development of atom chips. A high-performance computing cluster is available for computing intensive modelling and simulation tasks.

 Understanding the valency of single atoms on surfaces

From our earliest lessons in chemistry, we’re told that the electronic configuration, or valency, of an isolated atom is fixed by nature. We know, for instance, that the electronic configuration of phosphorus is always 1s22s22p63s23p3. And while this holds true for atoms in vacuum or free space, the reality is much more interesting for atoms residing on the surface of solids.

 Recently, we discovered that a single cobalt atom on a specific surface can take two distinct and stable valencies [1]. These valencies could be switched and read using the tip of a scanning tunnelling microscope, making it possible to store information within a single atom! For this single atom storage unit, we coined the term orbital memory.  

 Despite this development, there are still a lot of open questions regarding the underlying physics behind this orbital memory. To what temperatures are the valencies stable? Can it be observed for other atoms? Why hasn’t it been observed on other surfaces? If we bring two or more of these atoms next to one another, how does this new atomic degree of freedom couple interatomically? Finally, what if we build an artificial material from these atoms – what sort of properties would the resulting valency crystal have? Using state-of-the-art scanning probe techniques at a range of temperatures and with externally applied fields [2], this Ph.D. project will seek to answer these questions to peek inside the complicated life of electrons inside a single atom.

5-year funded PhD studentship: Artificial Synapses with Dual Opto-Electronic control for Ultra-Fast Neuromorphic Computer Vision

Closing Date: 31st June 2022

Applications are invited for a fully funded PhD studentship (3.5 years funded (tax-free stipend based on the UKRI rate (currently £15,609) + tuition fees ) within the School of Physics and Astronomy at the University of Nottingham.

Project title: Artificial Synapses with Dual Opto-Electronic control for Ultra-Fast Neuromorphic Computer Vision

Supervisory Team: Dr Neil Kemp (School of Physics and Astronomy), Professor Andrei Khlobystov (School of Chemistry), Dr Jesum Alves Fernandes (School of Chemistry),

Memristors (or resistive memory) are a new generation of electronic devices that directly emulate the chemical and electrical switching of biological synapses, i.e., the key learning and memory components of the human brain. Memristors also have the advantage of ultra-fast switching, low-power consumption (non-volatile operation), and nanoscale size (to give high density integration), and therefore have the potential to usher in a whole new era of artificial intelligence, devices, and applications. The aim of this project is to develop new state-of-the-art memristor devices that can switch optically as well as electronically, thereby enabling these “optically switching synapses” to be used as “in-memory” computing elements in neuromorphic circuits for computer vision applications. The work of the PhD will be to develop the basic switching circuit elements based on new optically active materials consisting of semiconducting nanowires/nanotubes coupled with metal nanoclusters and/or photoactive molecules, with enhanced light sensing capabilities that are suitable for integrating within memristor materials and devices. You will learn materials synthesis and deposition techniques, nanoscale device fabrication in a cleanroom environment as well as advanced electrical and optical characterization methods.

Working across the School of Physics and Astronomy (nottingham.ac.uk/physics/) and the School of Chemistry (nottingham.ac.uk/chemistry/) you will have access to a wide range of state-of-the-art facilities for the preparation and characterisation of novel materials and novel nanoscale devices. In addition, you will have access to the world-class suite of facilities of the Nanoscale and Microscale Research Centre (nottingham.ac.uk/nmrc/facilities/facilities.aspx).

We invite applications from candidates with knowledge and / or interest in nanoscale science, materials science, artificial intelligence and the optoelectronic properties of novel nanoscale materials and thin films.

Eligibility

  • Due to funding restrictions, the position is only available for home/UK candidates
  • Candidates must possess or expect to obtain, a 2:1 or first class degree in a Physical Sciences or Engineering related discipline.

PhD project area: Model-based approaches for magnetic resonance spectroscopy of the brain at ultra-high field

Supervisors: Dr. Adam Berrington, Prof. Michael Chappell

We are seeking an enthusiastic and motivated candidate to work on developing new capabilities for measuring the chemical composition of the brain with ultra-high field MR (7 T). 1H-MR spectroscopy (MRS) is a powerful technique to measure chemical composition of tissue non-invasively. At 7 T, several key neurochemicals have been shown to be detectable, which are of increasing interest in both neuroscience and clinical studies (e.g. in brain tumours and mental health). However, compared to MRI, MRS is a noisy technique which limits the ability to measure metabolites reliably in reasonable scan times.

The successful PhD candidate will develop and investigate model-based approaches for MRS, which may be used to accelerate MRS and improve quantification for whole brain metabolic imaging. There is also an opportunity to extend these approaches to measuring neurochemicals ‘dynamically’ over time during brain activation. The precise nature of the research can be tailored to the candidate’s own interests and there would be opportunities to work with clinicians and/or neuroscientists to exploit the developed imaging techniques. The candidate will have the opportunity to learn how to program pulse sequences on the MR scanner, develop their own analysis code, run human experiments and network with a range of academics outside of the UK. Candidates from a mathematical/natural sciences background are also encouraged to apply.

If you have any questions, or would like to chat about this opportunity, please contact Dr. Adam Berrington adam.berrington@nottingham.ac.uk


PhD project area: Development of sodium imaging

Supervisors: Prof Sue Francis, Dr Ben Prestwich

We are seeking a motivated and enthusiastic candidate to work on developing capabilities on sodium MRI.  Uniquely it is also possible to use MRI to image the amount of sodium in the skin and muscle using multinuclear 23Na imaging. 23Na MRI provides a method to assess skin sodium storage, and is a valuable tool in studying the effects of tissue sodium accumulation which is thought to change with age and hypertension, and in disease.

The successful PhD candidate will develop methods for sodium MRI and apply these techniques to the study of healthy volunteers and patient groups working with clinicians. This project will also use proton Magnetic Resonance Imaging (MRI) to image the skin and muscle and assess hydration status. The candidate will have the opportunity to learn how to program pulse sequences on the MR scanner, develop RF coils, and develop their own analysis code for sodium MRI, they will run human experiments and network with a range of academics.

This is a BBSRC CASE studentship with Unilever to commence in October 2022. As part of this the student will have the opportunity for a placement at Unilever and will attend the annual Unilever student workshops for training in industrial business skills & to facilitate cohort and network building.

If you have any questions, or would like to chat about this opportunity, please contact Prof Sue Francis susan.francis@nottingham.ac.uk or Dr Ben Prestwich ben.prestwich@nottingham.ac.uk.

Title: Model-based approaches for magnetic resonance spectroscopy of the brain at ultra-high field strength

We are seeking an enthusiastic and motivated candidate to work on developing new capabilities for measuring chemicals in the brain with ultra-high field MR (7 T). The successful candidate will join a vibrant and diverse interdisciplinary team at the Sir Peter Mansfield Imaging Centre (SPMIC) and work closely with experts across the University and Precision Imaging Beacon.

Project Background

Proton MR spectroscopy (MRS) is a powerful technique to measure chemical composition of tissue non-invasively. At 7 T, many brain chemicals are detectable, which are of increasing interest to both neuroscience and clinical studies (e.g. in brain tumours and mental health). For example, markers of key mutations in glioma have recently been shown to be detectable using MRS, potentially enhancing diagnostic ability alongside MR imaging. However, compared to MRI, MRS is a noisy technique which limits our ability to detect neurochemicals reliably across the brain in reasonable scan times.

Project Aims

The successful PhD candidate will develop and investigate model-based approaches for MRS, which will be used to improve the speed and robustness of MRS and improve quantification of neurochemicals for whole brain metabolic imaging. The project will involve designing and implementing MRS imaging sequences on the 7 T scanner and developing computational methods to process the resulting image data.  There is scope to tailor the nature of the research to the candidate’s own interests and there would be opportunities to work closely with clinicians and/or neuroscientists to exploit the developed imaging techniques. There is also an opportunity to extend imaging approaches to measuring neurochemicals over time during brain activation.

The candidate will have the opportunity to learn how to program pulse sequences on the ultra-high field MR scanner, develop their own analysis code, run human MR experiments and network with a range of academics outside of the UK.

Eligibility

  • Funding is only available for UK-based students
  • Candidates are expected to have, or be on track to obtain, a minimum of an upper second class honours in a relevant discipline such as physics, engineering, computer science, mathematics or related area.

Previous research experience as well as scientific programming (e.g. Python/Matlab) is desirable.
