Superradiance of Degenerate Fermi Gases in a Cavity
Superradiance of Degenerate Fermi Gases in a Cavity
In this Letter we consider spinless Fermi gases placed inside a cavity and study the critical strength of a pumping field for driving a superradiance transition. We emphasize that the Fermi surface nesting effect can strongly enhance the superradiance tendency. Around certain fillings, when the Fermi surface is nearly nested …
