SCALING IN FAST QUANTUM QUENCH

In recent years the problem of quantum quench in the vicinity of critical points has been investigated using holographic methods. This has led to an understanding of decoupling of length scales in the dynamics of slow quench and the emergence of Kibble-Zurek scaling, and provided predictions for corrections to the leading scaling behavior. In the other limit, holographic calculations have led to the discovery of new scaling laws for fast quench, which have been subsequently shown to be generic properties of deformations of any conformal field theory regardless of holography. This talk will discuss the salient aspects of this development.
