Short-time kinetics and initial correlations in nonideal quantum systems

Short-time kinetics and initial correlations in nonideal quantum systems

There are many reasons to consider quantum kinetic equations describing the evolution of a many-particle system on ultrashort time scales, e. g. correct energy conservation in nonideal plasmas, buildup of correlations (bound states), and kinetics of ultrafast processes in short-pulse laser plasmas....
