SUMMARY:Webinar: Stephan De Bievre - Approach to equilibrium: a case study in a quantum optics model
LOCATION:Zoom
DESCRIPTION:Stephan De Bievre– Université de Lille (https://www.univ-lille.fr/) \n \nWe
 dnesday, January 29th , 10:45AM EST\n \nApproach to equilibrium: a case stu
 dy in a quantum optics model\n \nApproach to equilibrium is the phenomenon 
 whereby large isolated systems with many degrees of freedom evolve, from al
 most any initial condition, asymptotically in time, towards thermodynamic e
 quilibrium; it lies at the heart of thermodynamics. Rigorously proving the 
 occurrence of this phenomenon in classical or quantum (model) systems remai
 ns a difficult task. We will in this talk report on progress on a simpler p
 roblem, which consists in showing circumstances in both classical and quant
 um systems under which a small system is driven to thermal equilibrium as t
 he result of its coupling to a large reservoir, which is itself out of equi
 librium. This phenomenon of the emergence of equilibrium in the small syste
 m is distinct from the much better understood phenomenon of return to equil
 ibrium, in which the reservoir is in equilibrium initially.\nThe talk is ba
 sed on joint work with M. Merkli, C. Mejia-Monasterio and P. Parris.\n
