Abstract

The terahertz response of a two-dimensional electron gas (2DEG) is investigated theoretically. The developed microscopic model shows that the terahertz absorption sensitively detects Coulomb-induced many-body correlations within the entire 2DEG system. In particular, the resulting response follows from a nontrivial competition between the ponderomotive and the Coulomb-correlation contributions. The result is in good agreement with recent experiments while the response cannot be explained with a simple Drude-model analysis..
