Abstract

A new treatment is presented for the generalized response of a physical system in a nonequilibrium state resulting from photoexcitation, using reduced density operators to account for dissipative dynamics, and developed so that it can be applied to physical systems starting from their atomic composition and their electronic structure obtained by ab initio calculations. This requires generation ...
