1209.3816 (Victor Gurarie)

Large time dynamics and the generalized Gibbs ensemble    [PDF]

Victor Gurarie
We study the large time dynamics of quantum systems under a sudden quench. We show that, first of all, for a generic system in the thermodynamic limit the Gibbs distribution correctly captures its large time dynamics. For an integrable system, the generalized Gibbs ensemble captures its large time dynamics only if the system can be thought of as a number of noninteracting uncorrelated fermionic degrees of freedom.
