  1. 37. Quantum Quench Dynamics
    Giuseppe Mussardo (TS)
    16/09/2014, 14:30
    Plenary Talk
    I will discuss in simple terms some topics emerging from recent studies of quantum systems driven away from equilibrium. Particular emphasis will be given to the integrable/non-integrable nature of the Hamiltonian and to its local properties.

    Talk
    Interactions are known to have dramatic effects on bosonic gases in low dimension: Not only does the ground state transform from a condensate-like state to an effective Fermi sea, but new fundamental excitations are predicted to appear which do not have any higher-dimensional equivalents. In this work, we trace these elusive excitations via their effects on the dynamical structure factor of...

  3. 28. Correlations after quantum quenches in the XXZ spin chain: Failure of the Generalized Gibbs Ensemble

    Talk
    In closed integrable systems, thermalization after a quantum quench is precluded by the existence of infinitely many conserved charges. The idea of the generalized Gibbs ensemble (GGE) is to include all local conserved charges into the canonical density operator with appropriate Lagrange-multipliers to ensure conservation of local charges. It is a nontrivial question whether the GGE correctly...
