Abstract

A microscopic theory for the nonlinear terahertz response of excited semiconductor systems is presented. It is shown that the measurable quantities in typical terahertz transmission/reflection experiments contain large ponderomotive contributions which mask the signatures from terahertz-induced many-body transitions. A scheme is developed to remove the ponderomotive contributions and applied to isolate the signatures of Rabi oscillations of an exciton population.
