We elucidate the role of the effective range in the Bose-Einstein-condensate (BEC) to
Bardeen-Cooper-Schrieffer (BCS) crossover regime of two-component fermions in three …

Recently the authors have developed an effective field theory formalism to systematically
describe cold fermionic gases near the unitary limit. The theory has enhanced predictive …

En esta tesis se investigan las propiedades del estado base de un gas de Fermi de dos
componentes homogéneo y balanceado. Se describe un gas atómico ultrafrıo donde hay un …
