The School of Physics at the University of Bristol is seeking a Research Associate (RA) to work on the theory of non-equilibrium steady states (NESS) in quantum many-body systems. The successful candidate will join the multi-disciplinary environment of the Theoretical Physics Group working under the supervision of Dr Stephen R. Clark. The research will be focused on NESS arising in a small interacting quantum system coupled to two or more thermal reservoirs with differing temperatures and chemical potentials. At the nanoscale quantum coherence, dissipation and correlations strongly influence the fluctuations and entropy production in the NESS. The RA will be central to the development and application of powerful simulation techniques for quantum many-body NESS aimed at unravelling these features. Specifically, the RA will investigate the interplay between interactions and dissipation on the efficiency of quantum thermal machines, the emergence of Floquet heating in periodically driven many-body systems, and potential experimental diagnoses of irreversibility at the quantum level.
This is 48 month post is part of the QuamNESS project on “Non-Equilibrium Steady-States of Quantum many-body systems: uncovering universality and thermodynamics” lead by Dr Clark at the University of Bristol in collaboration with Prof Mauro Paternostro at Queen’s University Belfast and Dr John Goold at Trinity College Dublin. The team have recently been awarded £1.6M in total from the UK’s Engineering and Physical Sciences Research Council and the RoI’s Science Foundation Ireland (see http://www.bristol.ac.uk/news/2020/august/quantum-thermodynamics.html). Frequent project meetings including longer stays in both Belfast and Dublin are expected. Also, the team will work with leading experimentalists in Mainz and Oxford to devise proposals for ion-trap and carbon nanotube implementations of quantum engines.
Previous experience with open quantum systems theory, e.g. quantum trajectories and Lindblad master equations, as well as tensor networks methods, e.g. density matrix renormalization group (DMRG) and time-evolving block decimation (TEBD), is essential. Prior experience with strongly correlated electronic models, such as the Hubbard and Anderson impurity models, is strongly desired. Familiarity with other related computational methods such Keldysh field theory and non-equilibrium Green functions would also be desirable. Good written and oral English language skills are required.
A PhD qualification in theoretical physics, or a closely related discipline (or equivalent professional qualification/experience), needs to be completed prior to taking up this position. Candidates in the final stages of completing their degree are encouraged to apply, if they can provide a reference attesting that their PhD viva will be held by the end of January 2020, or shortly thereafter.
Informal enquiries can be made to Dr Stephen Clark, firstname.lastname@example.org
