While the effect of spin-orbit coupling on struction in which the nested portions are gapped and the single-particle physics in 2D semiconductor quantum wells unnested portions form Fermi arcs, so that the ordered has been studied in several recent experimental and the- phases are metallic. Subjects: Quantum Gases () [3] arXiv:1512.00160 [ pdf , other ] Title: Quench dynamics of a Bose-Einstein condensate under synthetic spin-orbit coupling. We develop a method for creating two- and one-dimensional (2D and 1D) self-trapped modes in binary spin-orbit-coupled Bose-Einstein condensates with the contact repulsive interaction, whose local strength grows sufficiently rapidly from the center to the periphery. In particular, an exact semi-vortex (SV) solution is found for the anti-Gaussian radial modulation profile. The exact modes are.

Pairing superfluidity in spin-orbit coupled ultracold Fermi gases.

A review of physical processes related to disorder in spin-orbit coupling in two-dimensional electron gas is presented.... [42], and hence the spin relaxation requires a special analysis. Indeed, localized single electron states are spin degenerate in the absence of an external magnetic field and the spin decoherence is possible due to. 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.

Degenerate quantum gases with spin–orbit coupling: a review.

We explore these questions—and more—via the quantum simulation of many-body physics with quantum gases of dysprosium, the most magnetic element. Our group has pioneered the creation and study of Bose and Fermi-degenerate Dy gases. In our experiments, we exploit the long-range and anisotropic character of the dipole-dipole interaction among. TLDR. It is shown that investigating SO coupling in cold atom systems can enrich the understanding of basic phenomena such as superfluidity, provide a good platform for simulating condensed matter states such as topological superfluids and result in novel quantum systems such as SO coupled unitary Fermi gas and high spin quantum gases. 367.

(PDF) Spin-orbit coupling in quantum gases - ResearchGate.

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. Abstract We study quasi-two-dimensional dipolar Bose gases in which the bosons experience a Rashba spin-orbit coupling. We show that the degenerate dispersion minimum due to the spin-orbit coupling, combined with the long-range dipolar interaction, can stabilize a number of quantum crystalline and quasicrystalline ground states. 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. The single particle dispersion is mapped out by using momentum-resolved radio-frequency spectroscopy. From momentum.

Europe PMC is an archive of life sciences journal literature. The collective dipole mode is induced and measured in a spin-orbit (SO) coupled degenerate Fermi gas of 173 Yb atoms. Using a differential optical Stark shift, we split the degeneracy of three hyperfine states in the ground manifold, and independently couple consecutive spin states with the equal Raman transitions. In this review we will discuss the experimental and theoretical progresses in studying spin-orbit coupled degenerate atomic gases during the last two years. We shall first review a series of pioneering experiments in generating synthetic gauge potentials and spin-orbit coupling in atomic gases by engineering atom-light interaction. Realization of spin-orbit coupled quantum gases opens a new. We study quantum degenerate ultra-cold Fermi gases in the presence of artificial spin-orbit coupling and crossed Zeeman fields. We emphasize the case where parity is violated in the excitation spectrum and compare it with the simpler situation where parity is preserved. We investigate in detail spectroscopic properties such as the excitation spectrum, the spectral function, momentum.

Density-dependent spin-orbit coupling in degenerate quantum gases.

We report the observation of synthesized spin-orbit coupling (SOC) for ultracold spin-1 87Rb atoms. Different from earlier experiments where a one dimensional (1D) atomic SOC of pseudo-spin-1/2 is. PDF - This review focuses on recent developments on studying synthetic spin-orbit (SO) coupling in ultracold atomic gases. Two types of SO coupling are discussed. One is Raman process induced coupling between spin and motion along one of the spatial directions, and the other is Rashba SO coupling. We emphasize their common features in both single-particle and two-body physics and their.

Dynamical phases in quenched spin-orbit-coupled degenerate Fermi gas.

We measure momentum-resolved Raman spectra of a spin-polarized degenerate Fermi gas of 173Yb atoms for a wide range of magnetic fields, where the atoms are irradiated by a pair of counterpropagating Raman laser beams as in the conventional spin-orbit coupling scheme. Double resonance of first- and second-order Raman transitions occurs at a certain magnetic field and the spectrum exhibits a.. 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.

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.

These quantum simulators can be considered as Fermi gases with a specific synthetic spin-orbit coupling [118] [119] [120], mimicking the coupling of the intrinsic angular momentum of the electron. One of the most important aspects of ultracold quantum gases is that the interaction can be tuned, which enable the realization of mobility edge in 3-dimensional quantum gases 5. The superconducting-localization transition in a system without spin-orbit coupling (SOC) has been studied 9 , 12 , 14 , 15 , 17 , 18 by other researchers.
