title = "Nonequilibrium and many body effects in the realistic simulation of intersubband emitters",
abstract = "The influence of the many-body effects on the gain and the absorption spectrum of quantum cascade lasers was discussed. It was found that the gain was evaluated from the imaginary part of the susceptibility that was obtained by linear response calculations. The many-body effects depended on the occupations of the subbands and on the detailed Coulomb matrix elements that described the overlap of electronic wavefunctions. The results show that the microscopic treatment of quantum cascade lasers are of great importance for a quantitative description of such devices.",
