报告摘要：

Systems with time dependent couplings which interpolate between constant values and involve critical points are expected to display universal scaling. The AdS/CFT correspondence has 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.
