Developments in the physics of 2D electron systems during the last decade revealed a new
class of nonequilibrium phenomena in the presence of a moderately strong magnetic field …

Recent advances in optical studies of condensed matter systems have led to the emergence
of a variety of phenomena that have conventionally been studied in the realm of quantum …

Graphene is a recently discovered carbon-based material with unique physical properties.
This is a monolayer of graphite, and the two-dimensional electrons and holes in it are …

Two-dimensional electron systems subjected to a perpendicular magnetic field absorb
electromagnetic radiation via cyclotron resonance (CR). Here we report a qualitative …

The polarization dependence of the low field microwave photoconductivity and absorption of
a two-dimensional electron system has been investigated in a quasioptical setup in which …

We report on the observation of collective radiative decay, or superradiance, of cyclotron
resonance (CR) in high-mobility two-dimensional electron gases in GaAs quantum wells …

Electromagnetic response of a finite-width two-dimensional electron stripe is theoretically
studied. It is shown that retardation and radiative effects substantially modify the absorption …

We calculate the absorption spectra of a conductive disk in the presence of a metal gate. In
our analysis, we use the conductivity described by the Drude model. We examine the …

The microwave response of a two-dimensional electron system (2DES) covered by a
conducting top gate is investigated in the relativistic regime for which the 2D conductivity σ 2 …

We experimentally demonstrate that above 300 GHz, the plasmonic phase shifter can
operate at up to room temperature. We investigate the temperature-dependent behavior of …
