Comparison between a diagrammatic theory for the BCS-BEC crossover and Quantum Monte Carlo results
arXiv:cond-mat/0410578 · doi:10.1103/PhysRevB.72.012506
Abstract
Predictions for the chemical potential and the excitation gap recently obtained by our diagrammatic theory for the BCS-BEC crossover in the superfluid phase are compared with novel Quantum Monte Carlo results at zero temperature now available in the literature. A remarkable agreement is found between the results obtained by the two approaches
