Title: Thermalization in the AdS/CFT duality

Location: **V-155, VR-II**

Time: **Monday**, May 18, at 15:00-16:00.

### Abstract:

The AdS/CFT duality relates the dynamics of certain strongly interacting quantum field theories to the dynamics of certain gravitational theories in spacetimes with one higher dimension. Thus, it provides an interesting tool in which one can approach unsolved questions in either side by rephrasing them in the dual theory. One hope is to learn about the long standing problem of non-equilibrium dynamics in strongly interacting quantum field theories using the gravitational description. I will describe some work towards this goal. More precisely, by studying a few relatively simple examples, I will describe how the process of thermalization in the strongly coupled quantum field theory is captured in the gravitational description.
