A quantum mechanical theory of single-particle motion under the influence of a stochastic potential is presented. By solving the Dyson equation, the one-particle Green's function can be determined approximately. Assuming a Gaussian distribution, an explicit expression is derived for the spectral fun
A combined exciton-cyclotron resonance is found in the photoluminescence excitation and reflectivity spectra of semiconductor quantum wells with an electron gas of low density. In external magnetic fields an incident photon creates an exciton in the ground state and simultaneously excites an electro
