    Hartree-fock Semiconductor Bloch Equations and charge density correlations [Articol]
    (2002) Klyukanov, Alexandr; Loiko, Natalia; Babushkin, Ihar; Gurau, Virginia
    Generalized Semiconducor Bloch Equations are derived with using the fluctuation-dissipation theorem. Four op- erator expectation values like density-density correlators are calculated with account of coherent memory effects. Interactionswith mixed plasmon-phonons modes and excitonic effects are taken into account. Comparison with different other theoretical approaches is provided. Numerical calculations of the spontaneous radiationproduced by interband multiplasmon recombination of electron-hole pairs are fulfilled in dependence on the temperatureand plasmaconcentration. It is shown that the intensity maximum of spontaneous radiationshifted to the region of the first LO-phonon satellite with increasing of concentration in accordance with experiments [19,21].
