Collisional stability of a three-component degenerate fermi gas.
We report on the creation of a degenerate Fermi gas consisting of a balanced mixture of atoms in three different hyperfine states of 6Li. This new system consists of three distinguishable fermions with different and tunable interparticle scattering lengths a_{12}, a_{13}, and a_{23}. We are able to prepare samples containing 5x10;{4} atoms in each state at a temperature of about 215 nK, which c...
متن کاملPairing in a two-component ultracold Fermi gas: Phases with broken-space symmetries
We explore the phase diagram of a two-component ultracold atomic Fermi gas interacting with zero-range forces in the limit of weak coupling. We focus on the dependence of the pairing gap and the free energy on the variations in the number densities of the two species while the total density of the system is held fixed. As the density asymmetry is increased, the system exhibits a transition from...

متن کاملPairing and phase separation in a polarized Fermi gas.
We report the observation of pairing in a gas of atomic fermions with unequal numbers of two components. Beyond a critical polarization, the gas separates into a phase that is consistent with a superfluid paired core surrounded by a shell of normal unpaired fermions. The critical polarization diminishes with decreasing attractive interaction. For near-zero polarization, we measured the paramete...
متن کاملFulde–Ferrell pairing instability in spin–orbit coupled Fermi gas
We consider finite-momentum pairing of a superfluid ultracold Fermi gas subject to spin–orbit coupling and an effective Zeeman field. Based on our two-body and mean-field many-body calculations, we show that the Fulde–Ferrell-type superfluid dominates in both zeroand finite-temperature phase diagrams. We examine the origin and properties of this novel phase systematically. 3 Author to whom any ...
