Temperature of a trapped unitary Fermi gas at finite entropy
Abstract
We present theoretical predictions for the equation of state of a harmonically trapped Fermi gas in the unitary limit. Our calculations compare Monte Carlo results with the equation of state of a uniform gas using three distinct perturbation schemes. We show that in experiments the temperature can be usefully calibrated by making use of the entropy, which is invariant during an adiabatic conversion into the weakly interacting limit of molecular BEC. We predict the entropy dependence of the equation of state.

Unitary Fermi gas at finite temperature in the {epsilon} expansion
Thermodynamics of the unitary Fermi gas at finite temperature is investigated from the perspective of the expansion over {epsilon}=4d with d being the dimensionality of space. We show that the thermodynamics is dominated by bosonic excitations in the low temperature region T<<T{sub c}. Analytic formulas for the thermodynamic functions as functions of the temperature are derived to the lowest order in {epsilon} in this region. In the high temperature region where T{approx}T{sub c}, bosonic and fermionic quasiparticles are excited. We determine the critical temperature T{sub c} of the superfluid phase transition and the thermodynamic functions around T{sub c} to themore » 
FiniteTemperature Pairing Gap of a Unitary Fermi Gas by Quantum Monte Carlo Calculations
We calculate the onebody temperature Green's (Matsubara) function of the unitary Fermi gas via quantum Monte Carlo, and extract the spectral weight function A(p,omega) using the methods of maximum entropy and singular value decomposition. From A(p,omega) we determine the quasiparticle spectrum, which can be accurately parametrized by three functions of temperature: an effective mass m*, a meanfield potential U, and a gap DELTA. Below the critical temperature T{sub c}=0.15epsilon{sub F} the results for m*, U, and DELTA can be accurately reproduced using an independent quasiparticle model. We find evidence of a pseudogap in the fermionic excitation spectrum for temperatures upmore » 
Finitetemperature momentum distribution of a trapped Fermi gas
We present measurements of the temperaturedependent momentum distribution of a trapped Fermi gas consisting of {sup 40}K in the BCS to BoseEinstein condensation crossover regime. Accompanying theoretical results based upon a simple meanfield ground state are compared to the experimental data. Nonmonotonic effects associated with temperature T arise from the competition between thermal broadening and a narrowing of the distribution induced by the decrease in the excitation gap {delta}(T) with increasing T. 
Dynamical properties of a trapped dipolar Fermi gas at finite temperature
We investigate the dynamical properties of a trapped finitetemperature normal Fermi gas with dipoledipole interaction. For the freeexpansion dynamics, we show that the expanded gas always becomes stretched along the direction of the dipole moment. In addition, we present the temperature and interaction dependences of the asymptotic aspect ratio. We further study the collapse dynamics of the system by suddenly increasing the dipolar interaction strength. We show that, in contrast to the anisotropic collapse of a dipolar BoseEinstein condensate, a dipolar Fermi gas always collapses isotropically when the system becomes globally unstable. We also explore the interaction and temperature dependencesmore »
