Holographic thermalization from colliding particles

The talk is devoted to the study of thermalization process in the boundary theory in AdS3/CFT2 holographic setting. We discuss the dynamical picture of black hole formation in the bulk and describe it holographically by analyzing the behavior of correlation functions in the boundary theory. We observe that the calcuulation of two-point correlators in geodesic approximation reproduces thermal behavior if winding geodsics are taken into account.
