Thermodynamics of Fermi gases close to unitarity

Joaquin Drut
Univ. of Washington

In this talk I will present the results of Monte Carlo calculations of the thermal properties of dilute Fermi gases at large scattering length (the so-called unitary regime). I will discuss the temperature dependence of the energy, chemical potential and condensate fraction, and comment on the critical temperature for onset of superfluidity. I will show a comparison of our data with other groups’ and with experiment, and show new data for systems away from unitarity.
