In this paper, I present a detailed theoretical study on how a nanostructure, such as a semiconductor-based two-dimensional electron gas (2DEG), interacts with a linearly polarised intense laser field. A tractable method in dealing with the time-dependent many-body problem has been developed, from which the electron Green's function, the electron density–density correlation function and the inverse dielectric function matrix for a 2DEG driven by intense laser fields have been obtained. Using these results, the influence of terahertz laser radiation on dynamical properties such as plasmon and optical spectra in a 2DEG is investigated. The results obtained from this study can be used for the case where the intense terahertz radiation is provided by recently developed free-electron laser sources.
