Contribution

It provides a first-principles analysis of the oscillation spectrum, identifying new high-frequency modes and validating results with the Quasi-Localized Charge approximation.

Findings

Six fundamental oscillation modes identified

High-frequency Bernstein-type oscillations observed

Good agreement with Quasi-Localized Charge approximation

Abstract

A first-principle study of the collective oscillation spectrum of a strongly correlated one-component plasma in a strong magnetic field is presented. The spectrum consists of six fundamental modes which are found to be in good agreement with results from the Quasi-Localized Charge approximation. At high frequencies additional modes are observed that include Bernstein-type oscillations and their transverse counterparts which are of importance for the high-frequency optical and transport properties of these plasmas.
