I will discuss the work initiated in collaboration with Peter Schuck and others on the imbalance of superfluid on the isospin asymmetric nuclear matter. The current understanding of the phase diagram of dilute nuclear matter which includes the phases with broken space symmetries will be discussed covering the temperature-density regime across the BCS-BEC crossover.
Quite generally, an imbalance between the densities of spin-up and spin-down fermions hinders pairing and superfluidity in two-component attractive Fermi gases. The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phase, in which pairs condense at a finite value of center-of-mass momentum to compensate for the mismatch of the two Fermi surfaces, was proposed many years ago as a possible superfluid...
In the present talk we review the properties of a spin-1/2 Bose-Einstein condensate (BEC) in presence of both longitudinal and transverse external fields. The system has very peculiar properties not only with respect to the single component BEC, but also with respect to BEC mixtures (where the atom number of each species is conserved). In particular the system can exhibit a para- to...
