Black hole formation in AdS and thermalization on the boundary

Description
Summary:We investigate black hole formation by a spherically collapsing thin shell of matter in anti-de Sitter (AdS) space. This process has been suggested to have a holographic interpretation as thermalization of the Conformal Field Theory (CFT) on the boundary of the AdS space. The AdS/CFT duality relates the shell in the bulk to an off-equilibrium state of the boundary theory which evolves towards a thermal equilibrium when the shell collapses to a black hole. We use two-point functions to obtain information about the spectrum of excitations in the off-equilibrium state, and discuss how it characterizes the approach towards thermal equilibrium. The full holographic interpretation of the gravitational collapse would require a kinetic theory of the CFT at strong coupling. We speculate that the kinetic equations should be interpreted as a holographic dual of the equation of motion of the collapsing shell. (Author)
