摘要
We present a quantum kinetic description of temperature relaxation in warm dense matter. Starting from a general balance equation, we show how kinetic, correlation, and exchange energies of electrons and ions are exchanged during the equilibration towards equilibrium. Different approximations for the electron-ion energy transfer rates are discussed. The approach is finally applied to heated solids and shock-compressed matter as investigated in recent warm dense matter experiments to estimate the minimum time needed between pump and probe pulses when investigating equilibrium properties.
