SUMMARY:Séminaire du LPTMS: Mario Collura - LPTMS\, salle 201\, 2ème éta
 ge\, Bât 100\, Campus d'Orsay - 9 Déc 14 11:00
DESCRIPTION:Interaction quenches in 1D Bose gas\nMario Collura\, SISSA Trie
 ste\nWe study the non-equilibrium quench dynamics from free to hard-core o
 ne-dimensional bosons\, in which the relation between modes is nonlinear\,
  and consequently Wick’s theorem does not hold. We provide exact analyti
 cal results for the time evolution of the dynamical density-density correl
 ation function. We prove that its stationary value is described by a Gener
 alized Gibbs Ensemble (GGE). We analyze the entanglement properties of the
  the asymptotic steady state after the quench providing exact analytical r
 esults for both the leading extensive parts and the subleading terms for t
 he entropies as well as for the cumulants of the particle number fluctuati
 ons. Finally\, we extended the quench protocol in the presence of a hard-w
 all confining potential. We characterize the density profile and the two-p
 oint fermionic correlation function in the stationary state as well as the
 ir full time evolution.
