The method of Green's functions for a time-dependent Hamiltonian in systems far off equilibrium

E. Heiner

Physica A: Statistical Mechanics and its Applications, 1991, vol. 178, issue 3, 510-527

Abstract: A Green' function method is outlined for open systems being used if the Hamiltonian depends sensitively on time. The method is applied to the quantum-mechanical treatment of the photon field for the problem of highly excited semiconductors. As a result, we obtain the creation of laser-induced n-dependent gaps, where n = 0, 1, 2, … are the eigenvalues of the photon number operator of the laser field.
