PDF Spin-Orbit Coupled Degenerate Fermi Gases - ResearchGate.
The spin-orbit-coupled Fermi gas consists of both atoms and weakly bound molecules, which may strongly interact with each other. Our prediction for the molecular response is still qualitatively valid, with the understanding that there would be an additional pronounced atomic response in the rf spectra. 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#39;s large electronic orbital angular momentum.
PDF Collective modes of spin-orbit-coupled Fermi gases in the repulsive regime.
A system of a two-component Fermi gas with and without a Zeeman field that breaks the population balance between the two components. A bound state Rashba pair emerges because of the spin-orbit interaction.... spin-orbit-coupled Fermi gases in both three dimensions 3D [7-19] and 2D [20-23], most of them having appeared very recently. Motivated by recent experimental breakthroughs in generating spin-orbit coupling in ultracold Fermi gases using Raman laser beams, we present a systematic study of spin-orbit-coupled Fermi gases con ned in a quasi-one-dimensional trap in the presence of an in-plane Zeeman eld which can be realized using a nite two-photon Raman detuning.

The coupling of the spin of electrons to their motional state lies at the heart of recently discovered topological phases of matter. Here we create and detect spin-orbit coupling in an atomic Fermi gas, a highly controllable form of quantum degenerate matter. We directly reveal the spin-orbit gap via spin-injection spectroscopy, which characterizes the energy-momentum dispersion and spin.

For many-fermion systems, it has been proposed that a spin-orbitcoupled Fermi gas can undergo a smooth crossover from the ordinary BCS/BEC superflu-idity to the Bose-Einstein.

We investigate Rashba spin-orbit coupled Fermi gases in square optical lattice by using the determinant quantum Monte Carlo DQMC simulations which is free of the sign-problem. We show that the Berezinskii-Kosterlitz-Thoules phase transition temperature is firstly enhanced and then suppressed by spin-orbit coupling in the strong attraction region.

Abstract: 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. Three dimensions, the ground state of the Fermi system is enriched by the SOC[1623]. In two dimensions, the superfluid phase of the spin-orbit coupled Fermi gas can be topologically nontrivial[2427]. Furthermore, there is topologically nontrivial phase separationTPS which is the coexistence of superfluid phases with different topo.

The two-dimensional spin-imbalanced Fermi gas subject to s-wave pairing and spin-orbit coupling is considered a promising platform for realizing a topological chiral-p-wave superfluid.In the BCS limit of s-wave pairing, i.e., when Cooper pairs are only weakly bound, the system enters the topological phase via a second-order transition driven by. The above two obstacles can be overcome using spin-orbit SO coupled degenerate Fermi gases with an in-plane Zeeman field. SO coupling is essential for many important phenomena in condensed matter physics22,23. In solid materials, SO coupling is induced by inversion symmetry breaking of the bulk structure24.
Long-Lived Spin-Orbit-Coupled Degenerate Dipolar Fermi Gas.
Simplicity we consider a uniform Fermi gas and neglect the weak harmonic trap in the 2D plane, whose effects can be incorporated using the local density approximation. The Hamiltonian for this uniform 2D spin-orbit-coupled degenerate Fermi gas can be written as H = H F H I H soc, 1 where H F = k, kC k C k 2 isthesingle. Spin-orbit coupling has been created in this manner in Bose-Einstein condensates [2,714] and degen- erate Fermi gases DFGs [1519] of alkali metals.

Spin-Orbit Coupled Degenerate Fermi Gases.
Recently a scheme has been proposed for generating the two-dimensional Rashba-type spin-orbit coupling SOC for ultracold atomic bosons in a bilayer geometry [S.-W. Su et al., Phys. Rev. A 93, 053630 2016]. Here we investigate the superfluidity properties of a degenerate Fermi gas affected by the SOC in such a bilayer system. Recently our group firstly observed the SO coupling in an atomic Fermi gas 40K in which lasers induce strong SO coupling [27], and a team in MIT describes the ob-servation of SO coupling in an atomic Fermi gas6Li and a direct spectroscopic measurement of the SO coupled dispersion relation [28].It is should emphasized that all experiments on.
