Quantum dynamics of frustrated spin systems

Please note that this is a self-funded research project.

Start date: 1 October 2019

Application deadline: applications are accepted all year round.


We will investigate the magnetic spin dynamics of bulk systems as quantum effects start to become relevant at low temperature.

We will do this by looking at spin relaxation using a variety of experimental probes. These range from neutrons and muons, where large particle accelerators are required to produce these particles which can then map out the fundamental properties, and laboratory based equipment.

In our School of Physics and Astronomy we have developed a high frequency susceptibility probe system which can operate from 50mK to 400K.

Project aims and method

You will focus on investigating frustrated materials with these techniques, specifically we will look at materials where emergent phenomena occur, for example in the spin ice systems we have investigated the occurrence of magnetic monopoles. This is where excitations out of the frustrated ground state create magnetic excitations that undergo a Coulomb interaction, this novel result can be used to demonstrate that Maxwells equations have a direct symmetry between electrical and magnetic charges.

In this project you will use a range of experimental techniques using dilution fridges and cryostats to probe the frequency response of the spin dynamics and then model the results based on the latest understanding in our field.

You will develop a range of skills covering experimental physics, modelling and project planning with opportunities to write papers and present work at international conferences.


You should have obtained, or be about to obtain a First or Upper Second Class UK Honours degree in Physics, or a related subject.

Alternatively, applicants with equivalent qualifications gained outside the UK will also be considered. Applicants with a Lower Second Class degree will be considered if they also have a Master’s degree.

Applicants whose first language is not English are normally expected to meet the minimum University requirements (eg 6.5 IELTS).

How to apply

Consideration is automatic upon applying for a Doctor of Philosophy in Physics and Astronomy with an October 2019 start date.

As you are applying for a self-funded project, you need to provide the following:

  • research proposal
  • personal statement
  • CV.
