Introduction
We invite applications for a fully funded PhD position in theoretical many-body quantum physics, with a focus on the role of symmetry and symmetry breaking in non-equilibrium systems. Drawing on tools and ideas from numerous different fields, this project will seek to discover universal aspects of symmetry in the relaxation of many-body quantum systems as well as investigate novel phenomena in a range of experimentally relevant systems.
Project details
The main research idea is to investigate local dynamical symmetry restoration and breaking in closed quantum systems. Much of the project will be devoted to answering basic question such as: Can local microscopic symmetry breaking destroy macroscopic symmetry restoration? Is it easier for a many-body quantum system to dynamically enhance or suppress charge fluctuations? These will be addressed through analytic means backed up by numerical simulations in a range of theoretical models. Throughout the project the student will:
- Gain expertise in analytic and numerical techniques necessary to describe free, non-equilibrium systems, including both discrete and continuous time dynamics.
- Expand upon these results by incorporating interactions. Develop an understanding of analytically tractable systems e.g. integrable models, dual unitary quantum circuits and random unitary dynamics.
- Develop numerical and analytical tools to explore more general interacting systems which can be checked at solvable points.

Benefits
The successful candidate will receive comprehensive research training including technical, personal and professional skills. All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College Researcher College, which provides support with high-quality training and career development activities.
Entry requirements
- A minimum of a 2:1 first degree in a relevant discipline/subject area with a minimum 60% mark in the project element or equivalent with a minimum 60% overall module average.
PLUS
- The potential to engage in innovative research and to complete the PhD within 3.5 years.
- A minimum of English language proficiency (IELTS academic overall minimum score of 6.5 with a minimum of 6.0 in each component).
Additional requirements
The successful candidate will have a strong background in theoretical physics, a strong academic record, and will be highly motivated. Familiarity with many body quantum physics is highly desirable while some experience with scientific computing is advantageous. We expect them to engage in activities within the Centre for Fluid and Complex Systems as well as to take active part in collaborations with our existing network, both in the UK and internationally.
How to apply
All applications require full supporting documentation, a covering letter, plus a 500 word supporting statement showing how the applicant’s expertise and interests are relevant to the project.
