Job description

We invite applications for a full-time postdoctoral position in High Energy Theory based at the Department of Physics and Astronomy of the University of Sussex.

This position is funded by the UK ‘Network of clocks for measuring the stability of fundamental constants’ consortium (QSNET). The consortium aims to build a network of dissimilar clocks to search for spatio-temporal changes in fundamental constants. Our partners in the network are the National Physical Laboratory, Imperial College London, and the University of Birmingham. 

The position is devoted to theoretical research in high energy physics broadly defined. We are particularly interested in applicants with broad research experience in beyond the standard model physics, particle-astrophysics, including dark matter, and cosmology and willing to work in close contact with atomic, molecular and optical (AMO) experimentalists. The postholder will work under the supervision of Prof. Xavier Calmet.

The postholder will benefit from close interactions with the ITCM Group at the University of Sussex led by Prof. Matthias Keller who is a member of QSNET. They will also benefit from the lively research environment of the Sussex Theoretical Particle Physics (TPP)  and Mathematical Physics (MP) groups.  TPP is also a member of the related consortium QUEST-DMC funded under the same Quantum Technology for Fundamental Physics programme of the Science and Technology Facilities Council. They will also benefit from the consortium’s network international partners, including theorists at the University of Delaware and at the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo.

Potential candidates are strongly encouraged to make informal contact with Prof. Xavier Calmet (
