Nonequilibrium thermodynamics and optimal cooling of a dilute atomic gas

Nonequilibrium thermodynamics and optimal cooling of a dilute atomic gas

Characterizing and optimizing thermodynamic processes far from equilibrium is a challenge. This is especially true for nanoscopic systems made of few particles. We here theoretically and experimentally investigate the nonequilibrium dynamics of a gas of few noninteracting Cesium atoms confined in a nonharmonic optical dipole trap and exposed to degenerate …
