Abstract

This paper summarizes the main steps of the derivation of a set of simple analytical expressions obtained after a series of consistent approximations, starting from a more complete nonequilibrium many-body Keldysh Green's functions equations describing the coupling of light with intersubband excitations. The approach is valid under inverted medium conditions for which Hamiltonian approaches based on bosonic approximations cannot be applied.
