Microwave photoconductivity of a two-dimensional electron gas due to intra-Landau-level transitions
Christian Joas, Juergen Dietel, Felix von Oppen
Motivated by a recent experiment, we study the microwave-induced photoconductivity of a two-dimensional electron gas arising from intra-Landau-level transitions within a model wher…

Parametric resonance of a two-dimensional electron gas under bichromatic irradiation
C. Joas, M. E. Raikh, F. von Oppen
In an ultrahigh mobility 2D electron gas, even a weak nonparabolicity of the electron dispersion, by violating Kohn's theorem, can have a drastic effect on dc magnetotransport unde…
