We demonstrate all-optical implementation of spin-orbit coupling (SOC) in a two-electron Fermi gas of Yb 173 atoms by coupling two hyperfine ground states with a narrow optical transition. Due to the SU (N) symmetry of the S 0 1 ground-state manifold which is insensitive to external magnetic fields, an optical ac Stark effect is applied to split the ground spin states, which exhibits a high.

In the large disorder limits, the increase of the strength of spin- orbit coupling will increase the mean superconducting order parameter. This phenomenon shows that the system is more insensitive to disorder.

FERMI GASES WITH SYNTHETIC SPIN–ORBIT COUPLING.

The two spin components of the Fermi gas are non-interacting by themselves, but the impurity has a tunable, spin-selective interaction with one of the spin species. Such a configuration is experimentally achievable by tuning close to a Feshbach resonance between the impurity atom and the relevant spin state of the Fermi gas. We examine the properties of a one-dimensional (1D) Fermi gas with attractive intrinsic (Hubbard) interactions in the presence of spin-orbit coupling and Zeeman field by numerically computing the. We study the ferromagnetic transition of a two-component homogeneous dipolar Fermi gas with 1D spin-orbit coupling (SOC) at finite temperature. The ferromagnetic transition temperature is obtained as functions of dipolar constant λd, spin-orbit coupling constant λSOC and contact interaction constant λs. It increases monotonically with these three parameters. In the ferromagnetic phase.

We study a homogeneous two-component dipolar Fermi gas with 1D spin-orbit coupling (SOC) at zero temperature and find that the system undergoes a transition from the paramagnetic phase to the ferromagnetic phase under suitable dipolar interaction constant λd, SOC constant λSOC and contact interaction constant λs. This phase transition can be of either 1st order or 2nd order, depending on.

We elucidate the itinerant ferromagnetism of a dipolar Fermi gas with a Raman-induced spin-orbit coupling by investigating the exotic phase diagrams. It is revealed that the dipolar interaction along with spin-orbit coupling can corroborate the formation of ferromagnetism and that the Raman coupling adversely eliminates the tendency to this ferromagnetism transition, which greatly transcends.

Spin-orbit coupling arises from a synthetic gauge field created by the adiabatic following of degenerate dressed states composed of optically coupled components of an atomic spin. A relatively long-lived spin-orbit-coupled Fermi gas, readily being realized with a narrow optical transition, allows to explore a single-minimum dispersion where three minima of spin-1 system merge into and to monitor collective dipole modes of fermions in the strong coupling regime.
