Mf. Pereira et K. Henneberger, MICROSCOPIC THEORY FOR THE INFLUENCE OF COULOMB CORRELATIONS IN THE LIGHT-EMISSION PROPERTIES OF SEMICONDUCTOR QUANTUM-WELLS, Physical review. B, Condensed matter, 58(4), 1998, pp. 2064-2076
A nonequilibrium Green's-function T-matrix approach is presented for t
he consistent computation of semiconductor quantum-well optical spectr
a including strong Coulomb correlations in the coupled photon and carr
ier system. Numerical solutions of the Bethe-Salpeter-type equations y
ield good agreement with recent absorption and/or gain and emission ex
periments.
