Spin-Orbit Coupled Degenerate Fermi Gases.
Cold atoms with laser-induced spin-orbit (SO) interactions provide a platform to explore quantum physics beyond natural conditions of solids. Here we propose and experimentally realize two-dimensional (2D) SO coupling and topological bands for a rubidium-87 degenerate gas through an optical Raman lattice, without phase-locking or fine-tuning of optical potentials. Spin-orbit coupling has been created in this manner in Bose-Einstein condensates [2,7-14] and degen- erate Fermi gases (DFGs) [15-19] of alkali metals. Theseachievementsopennewavenuestoexperimentally study topological matter not realizable in the solid state [20,21].

The topology of Fulde-Ferrell (FF) superfluids with nonzero momentum pairings have never been explored until recent findings that FF superfluids in a spin-orbit (SO) coupled Fermi gas can accommodate Majorana fermions in real space in low dimensions and Weyl fermions in momentum space in three dimension. The case of Rashba spin-orbit coupling [16,20,31-35], while more recent theoretical work has considered the equal mixture of Rashba and Dresselhaus spin-orbit coupling considered here [36,37]. We generate spin-orbit coupling in a Fermi gas by dressing the jf¼9=2;m F ¼ 7=2ij"i and jf¼9=2; m F ¼ 9=2ij#i hyperfine spin states of 40K's.

Chiral topological phase 2d fermi gas with spin orbit coupling.
We consider a trapped atomic system in the presence of spatially varying laser fields. The laser-atom interaction generates a pseudospin degree of freedom (referred to simply as spin) and leads to an effective spin-orbit coupling for the fermions in the trap. Reflections of the fermions from the trap boundaries provide a physical mechanism for effective momentum relaxation and nontrivial spin. PDF - Spin-Orbit Coupled Degenerate Fermi Gases. 1.

In this paper, we investigate the phase diagram of the interacting Fermi gas with Rashba-type SOC on a square optical lattice. Such a system can be described by the spin-orbit (SO) coupled fermionic Hubbard model, see equation. We show that the SOC has important implications on the properties of MIT and phase diagram of this system. Recently, an ultracold Fermi gas has attracted much attention as a useful quantum simulator to study various many-body problems in strongly correlated Fermi systems [1-4].Using a tunable s-wave pairing interaction associated with a Feshbach resonance, we can now study the s-wave Fermi superfluid state from the weak-interacting BCS (Bardeen-Cooper-Schrieffer) regime to the strong-coupling..

We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate atoms using the most magnetic fermionic element, dysprosium. Spin-orbit-coupling arises from a synthetic gauge field created by the adiabatic following of degenerate dressed states comprised of optically coupled components of an atomic spin. Because of dysprosium's large electronic orbital angular momentum. Rashba-type spin-orbit coupling.

We study the dynamics of a non-degenerate, harmonically trapped Fermi gas following a sudden ramp of the spin-orbit coupling strength. In the non-interacting limit, we solve the Boltzmann equation in the presence of spin orbit coupling analytically, and derive expressions for the dynamics of an arbitrary initial spin state.
