Quantitative comparison between theoretical predictions and experimental results for the BCS-BEC crossover.

چکیده
Theoretical predictions for the Bardeen-Cooper-Schrieffer-Bose-Einstein condensation crossover of trapped Fermi atoms are compared with recent experimental results for the density profiles of 6Li. The calculations rest on a single theoretical approach that includes pairing fluctuations beyond mean-field. Excellent agreement with experimental results is obtained. Theoretical predictions for the zero-temperature chemical potential and gap at the unitarity limit are also found to compare extremely well with Quantum Monte Carlo simulations and with recent experimental results.

Heat Capacity of a Strongly-Interacting Fermi Gas: Supporting Online Material
The theoretical community is in the midst of unraveling the nature of resonantly interacting fermionic superfluids (S1–S9) with particular emphasis on the strongly interacting Fermi gas (S10). In the BCS-BEC crossover picture (S11), the strongly interacting Fermi gas is intermediate between the weak coupling BCS and BEC limits. In addressing the nature of the excitations from the conventional m...
متن کاملExperimental realization of BCS-BEC crossover physics with a Fermi gas of atoms
This thesis presents experiments probing physics in the crossover between BoseEinstein condensation (BEC) and BCS superconductivity using an ultracold gas of atomic fermions. Scattering resonances in these ultracold gases (known as Feshbach resonances) provide the unique ability to tune the fermion-fermion interactions. The work presented here pioneered the use of fermionic Feshbach resonances ...
متن کاملField-Theoretical description of the crossover between BCS and BEC in a non-Fermi superconductor
Using the field-theoretical methods we studied the evolution from BCS description of a non-Fermi superconductor to that of Bose-Einstein condensation (BEC) in one loop approximation. We showed that the repulsive interaction between composite bosons is determined by the exponent α of the Anderson propagator in a two dimensional model. For α 6= 0 the crossover is also continous and for α = 0 we o...

We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) superfluidity to Bose-Einstein condensation (BEC) in a two-dimensional Fermi gas at T = 0 using the fixed-node diffusion Monte Carlo method. We calculate the equation of state and the gap parameter as a function of the interaction strength, observing large deviations compared to mean-field predictions. In the BEC regime our resul...
متن کاملExtracting the condensate density from projection experiments with Fermi gases.
A debated issue in the physics of the BCS-BEC crossover with trapped Fermi atoms is to identify characteristic properties of the superfluid phase. Recently, a condensate fraction was measured on the BCS side of the crossover by sweeping the system in a fast (nonadiabatic) way from the BCS to the Bose-Einstein condensation (BEC) sides, thus "projecting" the initial many-body state onto a molecul...
