A. Brataas et al., THE EVOLUTION OF BERNSTEIN MODES IN QUANTUM WIRES WITH INCREASING DEVIATION FROM PARABOLIC CONFINEMENT, Journal of physics. Condensed matter, 8(26), 1996, pp. 4797-4804
We investigate the evolution of the interaction of the magnetoplasmon
resonance with the harmonics of the cyclotron resonance as the confine
ment of an electron gas in a quantum wire increasingly deviates from t
he parabolic case. The occurrence of the Bernstein modes is observed i
n a time-dependent Hartree model of a two-dimensional electron gas in
a single quantum wire.
