SUMMARY:Séminaire du LPTMS: Jacopo de Nardis - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 24 Nov 15 11:00
DESCRIPTION:Time evolution of out-of-equilibrium integrable models\nJacopo 
 de Nardis\, LPS ENS\n\nNon-equilibrium quantum mechanics has received a co
 nsiderable attention in the last years and in particular the dynamics obse
 rved after a quantum quench\, when a global parameter in the Hamiltonian o
 f the system is rapidly changed. We focus here on the post-quench time evo
 lution of the simplest interacting integrable models as the Lieb-Liniger d
 elta-Bose gas and the spin-1/2 XXZ spin chain. We address the problem of d
 etermining the steady state after a quench in the interaction strength and
  the time evolution towards it. While the steady state is determined by se
 ts of recently introduced quasi-local conserved quantities\, the time evol
 ution is related to the thermodynamic limit of the matrix elements and of 
 the overlap coefficients between the eigenstates of the model and the init
 ial state.\n\n\n\n\n\n
