FFLO Superfluids in 2D Spin-Orbit Coupled Fermi Gases.

. Spin-orbit (SO) coupling has led to numerously exciting phenomena in electron systems, for instance, the recently discovered topological insulator 1, 2. The synthesized SO coupling with ultracold neutral atoms opens a new avenue of quantum simulation 3-9, and gives us an opportunity to study SO coupling in bosonic systems.

FERMI GASES WITH SYNTHETIC SPIN-ORBIT COUPLING | Annual Review of Cold.

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. Zero-temperature mean-field chemical potential of a spin-orbit-coupled Fermi gas on the BCS side (1 / k F a s = − 1) and in the unitary limit (1 / k F a s = 0), calculated following the approach in Ref.. Here, we take a spin-orbit coupling strength λ k F / E F = 1, where k F and E F are the Fermi wave vector and Fermi energy, respectively. 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.

Spin-orbit coupling in Bose-Einstein condensate and.

In order to introduce spin-orbit coupling in neutral atomic gases, both Wang et al. and Cheuk et al. turned to a technique pioneered with bosonic Rubidium atoms [4]. While spin-orbit-coupled Bose gases have generated much excitement, Fermi gases hold even more promise. Due to the Pauli exclusion principle, fermions occupy a large number of.

Spin-Orbit Coupled One-Dimensional Fermi Gases with In nite Repulsion.

.. 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. In this paper, we demonstrate the dramatic e ect of the SOC on a strongly repulsive 1D spin-1/2 Fermi gas in a harmonic trap. We shall consider the type.

Spin-Orbit Coupled Degenerate Fermi Gases - NASA/ADS.

Abstract. 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 composed of optically coupled components of an atomic spin...

Spin-Injection Spectroscopyof a Spin-Orbit Coupled Fermi Gas.

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 also create a spin-orbit coupled lattice and probe its spinful band structure, which features additional spin gaps and a fully gapped spectrum. In the presence of s-wave interactions, such systems should display induced p-wave pairing, topological superfluidity, and Majorana edge states. 1. Cheuk, L. et al. Spin-Injection Spectroscopy of a.

Long-Lived Spin-Orbit-Coupled Degenerate Dipolar Fermi Gas.

Abstract. 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. Here we report the first experimental study of a spin-orbit coupled Fermi gas. We observe spin dephasing in spin dynamics and momentum distribution asymmetry in the equilibrium state as hallmarks. Reflections of the fermions from the trap boundaries provide a physical mechanism for effective momentum relaxation and nontrivial spin dynamics due to the emergent spin-orbit coupling. We explicitly consider evolution of an initially spin-polarized Fermi gas in a two-dimensional harmonic trap and derive nonequilibrium behavior of the spin.

Phase Diagram of a Spin-Orbit Coupled Dipolar Fermi Gas at T = 0 K.

Raman ﬁelds have previously been used to generate spin-orbit coupling and gauge ﬁelds in pioneering work on Bose-Einstein condensates [10–12] and, recently, spin-orbit coupling in Fermi gases [13]. Here, we directly measure the spinful band structure of Eq. (1), as well as the rich band structure of a spin-orbit coupled lattice. For. Made available by U.S. Department of Energy Office of Scientific and Technical Information. Abstract. We review our recent experimental realization and investigation of a spin-orbit (SO) coupled Bose-Einstein condensate (BEC) and quantum degenerate Fermi gas. By using two counter-propagating Raman lasers and controlling the different frequency of two Raman lasers to engineer the atom-light interaction, we first study the SO coupling.
