Pairing superfluidity in spin-orbit coupled ultracold Fermi gases.

We review some recent progresses on the study of ultracold Fermi gases with synthetic spin-orbit coupling. In particular, we focus on the pairing superfluidity in these systems at zero temperature. Recent studies have shown that different forms of spin-orbit coupling in various spatial dimensions can lead to a wealth of novel pairing superfluidity. A common theme of these variations is the. We investigate the harmonically trapped 2D fermionic systems with a effective spin-orbit coupling and intrinsic s-wave superfluidity under the local density approximation, and find that there is a critical value for Zeeman field. When the Zeeman field larger than the critical value, the topological superfluid phases emerge and coexist with the normal superfluid phase, topological phase. We show that spin-orbit coupling (SOC) gives rise to pairing instability in a highly polarized two-dimensional Fermi gas for an arbitrary interaction strength. The pairing instability can lead to a Fulde-Ferrell-Larkin-Ovchinnikov-like molecular state, which undergoes a first-order transition into a pairing state with zero center-of-mass.

Phase separation in a polarized Fermi gas with spin-orbit.

Furthermore, for a polarized Fermi gas, the SOC intro-duces competition against population imbalance, which can lead to topologically non-trivial phases [13, 16]. Re-cently, the phase diagrams for a polarized Fermi gas with spin-orbit coupling near a Feshbach resonance have been reported for a uniform gas [16]. The phase boundaries. We study the phase separation of a spin-polarized Fermi gas with spin-orbit coupling near a wide Feshbach resonance. As a result of the competition between spin-orbit coupling and population imbalance, the phase diagram for a uniform gas develops a rich structure of phase separation involving topologically nontrivial gapless superfluid states.

FERMI GASES WITH SYNTHETIC SPIN–ORBIT COUPLING.

We briefly review recent progress on ultracold atomic Fermi gases with different types of synthetic spin-orbit coupling, including the one-dimensional (1D) equal weight Rashba-Dresselhaus and two-dimensional (2D) Rasbha spin-orbit couplings. Theoretically, we show how the single-body, two-body and many-body properties of Fermi gases are dramatically changed by spin-orbit coupling. In.

FFLO superfluids in 2D spin-orbit coupled Fermi gases.

1. Integrated radio-frequency spectrum To create a strongly interacting Fermi gas with spin-orbit coupling, first, the bias magnetic field is tuned from high magnetic field above Feshbach resonance to a final value B (which is varied) below Feshbach resonance. Thus, Feshbach molecules are created in this process. 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 zero- and finite-temperature phase diagrams. We examine the origin and properties of this novel phase systematically. E. In quantum physics, the spin–orbit interaction (also called spin–orbit effect or spin–orbit coupling) is a relativistic interaction of a particle's spin with its motion inside a potential. A key example of this phenomenon is the spin–orbit interaction leading to shifts in an electron 's atomic energy levels, due to electromagnetic.

ArXiv:2003.13444v3 [] 17 Jun 2020.

Abstract: We study the phase separation of a spin polarized Fermi gas with spin-orbit coupling near a wide Feshbach resonance. As a result of the competition between spin-orbit coupling and population imbalance, the phase diagram for a uniform gas develops a rich structure of phase separation involving gapless superfluid states which are topologically non-trivial. We introduce a spin-orbit coupling scheme, where a retro-reﬂected laser beam selectively diffracts two spin components in opposite directions. Spin sensitivity is provided by sweeping through a magnetic-ﬁeld sensitive transition while dark states ensure that spontaneous emission remains low. The scheme is adiabatic and thus inherently robust.

We investigate the ground state of a uniform two-dimensional polarized Fermi gas with Rashba spin-orbit coupling at zero temperature. We construct the phase diagram by comparing the thermodynamic potential of superfluid and phase-separated states in detail. Due to the competition between polarization and spin-orbit coupling, we find that phase-separated states in the phase diagram can be.
