Contribution

It introduces a theoretical model showing magnetic field-induced oscillations in polariton linewidth and the ability to modulate scattering rates in microcavities.

Findings

Polariton linewidth oscillates with magnetic field strength.

Magnetic field can both decrease and increase scattering rates.

Potential applications in controlling polariton dynamics.

Abstract

We theoretically calculate the polariton linewidth associated with the polariton-electron scattering in a microcavity in presence of a magnetic field perpendicular to the microcavity plane. It is shown that the polariton linewidth oscillates as a function of the magnetic field magnitude and the polariton-electron scattering rate can be not only decreased but also increased by the magnetic field. The possible applications of such an effect are discussed.
