The evolution of Bernstein modes in quantum wires with increasing deviation from parabolic confinement

TL;DR

This paper studies how Bernstein modes evolve in quantum wires as their confinement deviates from the parabolic shape, using a time-dependent Hartree model to analyze electron gas interactions.

Contribution

It introduces a detailed analysis of Bernstein mode evolution in non-parabolic quantum wire confinement using a time-dependent Hartree approach.

Findings

Bernstein modes appear in non-parabolic quantum wire confinement.

Interaction of magnetoplasmon resonance with cyclotron harmonics changes with confinement shape.

The study provides insights into electron gas behavior in quantum wires with varying confinement.

Abstract

We investigate the evolution of the interaction of the magnetoplasmon resonance with the harmonics of the cyclotron resonance as the confinement of an electron gas in a quantum wire increasingly deviates from the parabolic case. The occurrence of the Bernstein modes is observed in a time-dependent Hartree model of a two-dimensional electron gas in a single quantum wire.
