Course Content: 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.

Course Objective: Overview of Large D gravity
Requirement / Prerequisite: --
Course Content: General Relativity is an old theory but its dynamics remains difficult to solve and understand, in particular when strongly-gravitating objects such as black holes are involved. Although at first sight it may seem an odd idea, I will argue that it is actually quite natural to investigate the properties of this theory and its black holes in the limit in which the number of spacetime dimensions D grows to infinity. The gravitational field localizes very strongly near the black hole horizons, which simplifies dramatically the description of their interactions and allows efficient calculational approaches in an expansion in 1/D. There are also hints that this limit may lead to a reformulation of the theory in terms of low-dimensional strings. In the first part of the lectures I will discuss the broad framework and motivation for the subject, and in the second part I will focus on the dynamics of black holes at large D. Technicalities will be introduced only when necessary.
