The University is dedicated to supporting an equitable, diverse, and inclusive environment - to create better futures, together. The diverse backgrounds, characteristics and opinions within our community are our great strength and are key to our pursuit of delivering educational excellence, enterprise, research and professional services. We welcome applications from people from diverse backgrounds and minoritized groups as they are currently under-represented within our community.
We recognise the value of a fulfilling and balanced work and personal life which promotes wellbeing. We seek to support colleagues in achieving this balance and have family-friendly policies, flexible working arrangements and many roles can be suitable for dynamic working arrangement. This includes considering applications to work on a part-time, flexible and job share basis wherever possible.
We are proud to be a Real Living Wage Employer—so much so that we go beyond the standard, providing additional supplementary payments at specific pay points to further support our employees' financial wellbeing. Further information about the Loughborough Real Living Wage Supplement can be found on our HR webpage.
Loughborough University is a UKVI Sponsor. Some individuals may require sponsorship to enable them to apply for a visa to provide them with the right to work in the UK. Please note certain roles are not eligible for sponsorship. For further information and eligibility please visit the UKVI website.
Loughborough University invites applications for a Postdoctoral Research Associate position in theoretical physics, for a duration of three years. The successful candidate will join the Department of Mathematical Sciences to work with Dr. Achilleas Lazarides on the research project "Constrained Quantum Systems", funded by the Leverhulme Trust.
The project aims to open new directions in many-body quantum dynamics by systematically constructing and analysing quantum systems with kinetic constraints — a promising, yet largely undeveloped, mechanism for ergodicity breaking and slow dynamics without disorder. Drawing inspiration from classical kinetically constrained models of glassy behaviour, we will develop quantum analogues that feature irreducible constrained dynamics, spatial asymmetry, and novel forms of dynamical arrest.
Key goals include identifying mechanisms for slow relaxation and non-ergodicity in translation-invariant quantum systems; classifying constrained dynamical universality classes; and developing analytical and numerical tools capable of probing highly non-trivial many-body dynamics.
The project will employ a range of techniques, including exact diagonalisation, Krylov subspace dynamics, random matrix-inspired methods, perturbative and variational approximations, and rigorous constraint-based arguments. There is substantial scope for theoretical innovation in both model development and analytical/numerical approaches.
We are looking for candidates with a strong research background in theoretical quantum many-body physics, statistical mechanics, non-equilibrium dynamics, or closely related areas. Applicants should have expertise in analytical and/or numerical methods for interacting quantum systems. Familiarity with constrained dynamics, kinetic constraints, glassy systems, or random matrix techniques would be an advantage but is not required.
The successful candidate will have the opportunity to shape the development of a new research direction at the interface of quantum dynamics and non-equilibrium statistical mechanics.
For informal enquiries, please contact Dr. Achilleas Lazarides Senior Lecturer in Applied Mathematics on A.Lazarides@lboro.ac.uk.
