Title: UNIVERSALITY IN QUANTUM QUENCH : FROM HOLOGRAPHY TO LATTICES

Abstract: Systems with time-dependent couplings which interpolate between constant values and involve critical points are expected to display universal scaling. Holographic methods have been used to understand some aspects of such quantum quenches, in particular, Kibble-Zurek scaling. In the opposite regime of fast quench, holographic methods have uncovered new scaling laws which have been subsequently shown to hold in general continuum quantum field theories. This talk reviews these developments and explores how these different scaling regimes appear in solvable lattice field systems in one and two space dimensions and relate to other known results for abrupt quenches. I will also discuss new scaling properties of the entanglement entropy in some one dimensional systems.
