PDF Collective modes of spin-orbit-coupled Fermi gases in the repulsive regime.

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 theoretically BEC-BCS crossover physics in the presence of Rashba spin-orbit coupling in 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. We study the properties of Rashba pairs using standard pair fluctuation theory. At.

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.

(PDF) Phase diagram of interacting Fermi gas in spin–orbit.

The interplay between spin-orbit coupling and atom-atom interactions plays the crucial role in the collective behaviors of Fermi gas. In contrast with ordinary Fermi liquid, spin-orbit-coupled Fermi gas has strongly correlated spin and density excitations. Within the scheme of random-phase approximation, we classify collective. 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.

. Coupled spin flips [3–5]. The adiabatic evolution of these dressed states as the atom movesin the Raman field creates a synthetic gauge field. This field takes the form of spin-orbit coupling when these states form a degenerate manifold [6]. Spin-orbit coupling has been created in this manner in Bose-Einstein condensates [2,7–14] and degen. In this Letter, we report the first experimental realization and investigation of a spin-orbit coupled Fermi gas. Both spin dephasing in spin dynamics and momentum distribution asymmetry of the equilibrium state are observed as hallmarks of spin-orbit coupling in a Fermi gas.

Rasbha spin-orbit coupled Fermi gas in the presence of both in-plane and out-of-plane Zeeman fields. By cal-culating the superfluid density tensor, we obtain the su-perfluid phase stiffness as functions of the temperature, spin-orbit coupling strength, binding energy (that char-acterizes the interatomic interaction strength), in-plane.

Number, the spin degeneracy is huge. Thus, no matter how weak the spin-orbit coupling is, there are a large number of excitations lying below the spin-orbit scale that will be strongly a ected.
