Electron Condensation in a Jellium Coupled to a Finite Photonic Cavity

TL;DR

This paper investigates how electrons in a jellium model localize into a condensed state when coupled to a finite photonic cavity, revealing a temperature-dependent phase transition driven by electron correlations.

Contribution

It introduces the concept of electron condensation in a jellium coupled to a finite cavity and identifies the temperature at which localization occurs due to enhanced correlations.

Findings

Electron localization occurs below a critical temperature T_0.

Coupling to a finite cavity enhances electron correlations.

Electron condensation is driven by correlation effects.

Abstract

We describe the process of electron condensation into a localized state in a structureless jellium that is coupled to a finite cavity. It is shown that there exists a temperature T_0 below which electrons within the jellium localize. This process is driven by enhancement of correlations between the electrons that are coupled to the cavity.
