报告摘要：

Systems withtime dependent couplings which interpolate between constant values and involve criticalpoints are expected to display universal scaling. The AdS/CFT correspondencehas been used to understand some aspects of such quantum quenches, inparticular Kibble-Zurek scaling. In the opposite regime of fast quench,holographic methods have uncovered new scaling laws which have beensubsequently shown to hold in general continuum quantum field theories. Thistalk reviews these developments.
