Phase diagram of a strongly interacting spin-imbalanced Fermi gas
We obtain the phase diagram of spin-imbalanced interacting Fermi gases from measurements of density profiles of Li atoms in a harmonic trap. These results agree with, and extend, previous experimental measurements. Measurements of the critical polarization at which the balanced superfluid core vanishes generally agree with previous experimental results and with quantum Monte Carlo (QMC) calcula...

متن کاملSpin-imbalanced quasi-two-dimensional Fermi gases.
We measure the density profiles for a Fermi gas of (6)Li containing N(1) spin-up atoms and N(2) spin-down atoms, confined in a quasi-two-dimensional geometry. The spatial profiles are measured as a function of spin imbalance N(2)/N(1) and interaction strength, which is controlled by means of a collisional (Feshbach) resonance. The measured cloud radii and central densities are in disagreement w...
متن کاملUniversal Fermi gases in mixed dimensions.
We investigate a two-species Fermi gas in which one species is confined in a two-dimensional plane (2D) or one-dimensional line (1D) while the other is free in the three-dimensional space (3D). We discuss the realization of such a system with the interspecies interaction tuned to resonance. When the mass ratio is in the range 0.0351<m_(2D)/m_(3D)<6.35 for the 2D-3D mixture or 0.006 46<m_(1D)/m_...
متن کاملMean-field phase diagrams of imbalanced Fermi gases near a Feshbach resonance
We propose phase diagrams for an imbalanced unequal number of atoms or Fermi surface in two pairing hyperfine states gas of atomic fermions near a broad Feshbach resonance using mean-field theory. Particularly, in the plane of interaction and polarization we determine the region for a mixed phase composed of normal and superfluid components. We compare our prediction of phase boundaries with th...
