Dicke-superradiance in electronic systems coupled to reservoirs

TL;DR

This paper presents a theoretical study of superradiance in semiconductor systems, showing how strong magnetic fields and reservoir coupling induce collective decay and novel oscillations.

Contribution

It introduces a new theoretical framework for superradiance in electronic systems coupled to reservoirs under magnetic fields.

Findings

Superradiance occurs in semiconductor structures with magnetic fields.

Reservoir coupling leads to oscillations with frequency proportional to the square root of the pumping rate.

Theoretical predictions suggest observable collective decay phenomena.

Abstract

We present theoretical results for superradiance, i.e. the collective coherent decay of a radiating system, in semiconductor structures. An optically active region can become superradiant if a strong magnetic field is applied. Pumping of electrons and holes at a rate T through coupling to external `reservoirs' leads to a novel kind of oscillations with frequency $\sim \sqrt{T}$.}
