Thermalization of the spectral function in strongly coupled two dimensional conformal field theories. (English) Zbl 1342.81476

Summary: Using Wigner transforms of Green functions, we discuss non-equilibrium generalizations of spectral functions and occupation numbers. We develop methods for computing time-dependent spectral functions in conformal field theories holographically dual to thin-shell AdS-Vaidya spacetimes.
