Stationary Solutions for the Excitonic Optical Stark Effect in Two and Three Dimensional Semiconductors
Band-edge absorption spectra for a probe beam under the action of a nonresonant pump beam are calculated and analyzed within a stationary Hartree-Fock theory. Due to many-body interactions one obtains an exciton optical Stark shift with an approximately constant (2d) or slightly increasing (3d) exciton oscillator strength in agreement with several recent experiments and in striking contrast to corresponding atomic observations. Apparently deviating results of earlier semiconductor experiments were partly caused by dynamical effects and partly by the presence of real excitations.
