The center of Theoretical Physics (CPHT) at Ecole Polytechnique gathers research scientists working in diverse domains of fundamental and applied Physics. The overall coherence is assured by the corpus of common, transposable, mathematical and numerical methods.

CPHT is on the campus of Ecole Polytechnique, buildings 5 and 6. The reception offices are located in "building 6" , offices 06.1046 and 06.1045.

Non-Equilibrium dynamics of Many Body Quantum Systems
 

the 8th of September 2016  at  2:30 PM

Conference Room, Building 6

 

Abstract: This thesis deals with the study of dynamical properties of out-of-equilibrium quantum systems. We introduce in particular a general class of Spin-Boson models, which describe for example light-matter interaction or dissipative phenomena. We contribute to the development of a stochastic approach to describe the spin dynamics in these models. In this context, the effect of the bosonic environment is encapsulated into additional stochastic degrees of freedom whose time-correlations are determined by spectral properties of the bosonic environment. We use this approach to study many-body phenomena such as the dissipative quantum phase transition induced by an ohmic bosonic environment. Synchronization phenomena as well as dissipative topological transitions are identified. We also progress in the study of arrays of interacting light-matter systems. These theoretical developments follow recent experimental achievements, which could ensure a quantitative study of these phenomena. This notably includes ultra-cold atoms, trapped ions and cavity and circuit electrodynamics setups. We also investigate hybrid systems comprising electronic quantum dots coupled to electromagnetic resonators, which enable us to provide a spectroscopic analysis of many-body phenomena linked to the Kondo effect. We also introduce thermoelectric applications in these devices.

Boris Altshuler, professor at Columbia University, is visiting Ecole Polytechnique for a  period of 6 months, starting end of january 2016. He has been appointed Visiting Professor  in the framework of the Columbia - Ecole Polytechnique - Alliance program,
see: http://alliance.columbia.edu/current-visiting-professors

Professor Altshuler has made pioneering contributions to theoretical condensed matter physics, especially on Anderson localisation, including localisation and interactions. In recent years, he initiated the study of "Many Body Localisation", which is currently a very active field of research.
For more details, see e.g.:

https://www.aps.org/programs/honors/prizes/prizerecipient.cfm?last_nm=Altshuler&first_nm=Boris&year=2003

During his visit to France, Boris Altshuler will share his time between the CPHT and IOGS on the Ecole Polytechnique campus, and the Institut de Physique du College de France. In April 2016, he will deliver a series of lectures on Anderson localisation and Many-Body Localisation, which will take place on the Ecole Polytechnique campus.
