TL;DR
This paper explores how Fermi gases can suppress spontaneous emission through quantum statistical effects, analyzing finite temperature and trap anisotropy impacts, and suggesting experimental approaches.
Contribution
It demonstrates the inhibition of spontaneous emission in Fermi gases considering realistic conditions like temperature and trap shape, and discusses potential experimental setups.
Findings
Fermi gases can inhibit spontaneous emission under certain conditions.
Finite temperature and trap anisotropy influence the degree of inhibition.
Potential experimental realizations are proposed.
Abstract
Fermi inhibition is a quantum statistical analogue for the inhibition of spontaneous emission by an excited atom in a cavity. This is achieved when the relevant motional states are already occupied by a cloud of cold atoms in the internal ground state. We exhibit non-trivial effects at finite temperature and in anisotropic traps, and briefly consider a possible experimental realization.
