This work compares several versions of the equations motion for a test particle encountering cyclotron resonance with single, field-aligned whistler mode wave. The gyro-averaged Lorentz equation produces both widespread phase trapping (PT) and “positive bunching” low pitch angle electrons by large amplitude waves. Approximations allow Hamiltonian description to be reduced single pair conjugate ...

Low temperature magnetotransport measurements and far infrared transmission spectroscopy are reported in molecular beam epitaxial grown twodimensional hole systems confined in strained InAs quantum wells with magnetic impurities in the channel. The interactions of the free holes spin with the magnetic moment of 5/2 provided by manganese features intriguing localization phenomena and anomalies i...

We present an interpretation of recent cyclotron resonance experiments on the two-dimensional electron gas in GaAs/AlGaAs heterostructures. We show that the observed dependence of the resonance spectrum on Landau level occupancy and temperature arises from the interplay of three factors: spin-splitting of the cyclotron frequency; thermal population of the two spin states; and coupling of the re...

The present paper reports on the RXTE observations of the binary X-ray pulsar 4U 0115+63, covering an outburst in 1999 March-April with 44 pointings. The 3−30 keV PCA spectra and the 15−50 keV HEXTE spectra were analyzed jointly for the cyclotron resonance features. When the 3−50 keV luminosity at an assumed distance of 7 kpc was in the range (5−13)×10 erg s, harmonic double cyclotron features ...
