Description
Quantum quench is considered in 2D CFT's with additional conserved
charges besides the hamiltonian. Local observables are shown to
thermalize to an ensemble average. The ensemble is universal in the
sense that is specified by only the conserved charges of the initial
state. The thermalization rate has a universal lower bound, which
depends on these conserved charges and some algebraic properties of
the most relevant operator of the CFT. A holographic interpretation of
these observations is provided in terms of higher spin black holes.
