We present a comprehensive theoretical formulation for magneto-optical properties in narrow-band-gap and zero-band-gap Hg Te-CdTe superlattices. It is found to be crucial that the details of the unique band structure be taken into account in full generality. Statistical factors also play a dominant role in the magneto-optical properties, since the location of the Fermi level determines which of...

: We report on the theoretical studies of a recently discovered strong radiation-induced magnetoresistance spike obtained in ultraclean two-dimensional electron systems at low temperatures. The most striking feature of this spike is that it shows up on the second harmonic of the cyclotron resonance. We apply the radiation-driven electron orbits model in the ultraclean scenario. Accordingly, we ...

In overdense plasma for which the plasma frequency exceeds the cyclotron frequency, X-mode, nearperpendicular cyclotron emission does not propagate to the outboard plasma edge. However, under these conditions it remains possible for electron Bernstein waves (EBWs) to transmit emitted radiation from central plasma to the plasma exterior via a mode conversion to electromagnetic waves near the pla...

[1] At various altitudes in the plasmasphere, sounder pulses from the Radio Plasma Imager (RPI) instrument on the IMAGE satellite can couple strongly to protons, a process revealed in echo time delay versus frequency forms that arrive at multiples of the local proton cyclotron period tp. Lower-altitude (<4000 km) versions of two of these proton cyclotron (PC) forms were previously observed in t...

We introduce a spin-orbit assisted electron-phonon e-ph coupling mechanism for carriers in semiconductor quantum wells and predict qualitatively the form and shape of anticrossings between the cyclotron resonance CR and optical LO and TO phonons. Since this e-ph interaction involves the electron spin it makes the predicted TO-CR anticrossing dependent on the filling factor and therefore on the ...

Cyclotron resonance is now applied as one of the important means for heating plasma in a fusion reactor. We examined this phenomenon from the viewpoint of electron gyration orbits through a solution of the linearized relativistic equation of motion. We found a powerful term that accelerates a relativistic charged particle largely at a resonance point when a magnetic field strength is very large...
