Ultracold fermion cooling cycle using heteronuclear Feshbach resonances
Ultracold fermion cooling cycle using heteronuclear Feshbach resonances
We consider an ideal gas of Bose and Fermi atoms in a harmonic trap, with a Feshbach resonance in the interspecies atomic scattering that can lead to the formation of fermionic molecules. We map out the phase diagram for this three-component mixture in chemical and thermal equilibrium. Considering adiabatic association …
