Topological superfluids in two-dimensional Fermi gas with Rashba spin-orbit coupling. By Xiaosen Yang, Ho-Kin Tang, Noah Fan Qi Yuan, Beibing Huang, Guangcan Guo, Ming Gong, Hai-Qing Lin. 2021-09-10. The realization of spin-orbit coupling (SOC) in ultracold atoms has triggered an intensive exploring of topological superfluids in the. The collective-mode excitation energy of a population-imbalanced spin-orbit-coupled atomic Fermi gas loaded in a two-dimensional optical lattice at zero temperature is calculated within the Gaussian approximation, and from the Bethe-Salpeter equation in the generalized random-phase approximation assuming the existence of a Sarma superfluid state. It is found that the Gaussian approximation.

Two-dimensional chiral topological superconductivity in.

The chiral p-wave superconductor in two dimensions (2D) and the closely related fractional quantum Hall Pfaffian state at filling fraction ν=5/2 are the archetypal examples of topologically ordered states of matter that support non-Abelian anyonic excitations 1,2,3.The theoretical exploration of these states has shaped our understanding of topological order and is foundational for the distant.

May 05, 2022 · Here the authors report a chiral spin texture around the Fermi level related to structural symmetry breaking in a TaSe2 layer grown on a Bi2Se3 surface.... the strong spin-orbit coupling. By analyzing DFT Fermi surface calculations, we found that the 243-T orbit was generated by the band crossing the Fermi energy along G-X, which also generates the nonsymmorphic point X and −0.5 eV. How-ever, the primary result of this work is that between 85° and 95°, the 243-T orbit has a p Berry phase (extracted by fitting the resistivity. Topological Fulde-Ferrell-Larkin-Ovchinnikov states in spin-orbit-coupled Fermi gases... can be stabilized in a 2D Fermi gas with Rashba spin-orbit coupling and both in-plane and out-of-plane Zeeman fields. The tFF state features a non-trivial Berry phase, along with unique properties that may be detected using existing experimental techniques.

(PDF) Topological phase transitions between chiral and helical.

Weyl points usually arise when two bands of spin-polarized bands cross in semimetals. The challenge of realizing practical devices with topological semimetals is that their high carrier density makes it difficult to modulate the position of their Fermi level (E F) and chiral anomaly current, which also results in high static power consumption.

Chiral spin waves in Fermi liquids with spin-orbit coupling.

The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance R xy exhibits steps that take on the quantized values. Superconductor with strong spin-orbit coupling, when arranged in a 2D lattice, can yield a 2D topological chiral p-wave superconductor whose chiral Majorana edge modes can be observed in scanning tunneling microscope measurements. To shed light on the rich range of possibilities, we analyse the topological properties of a system with dense. Spin–orbit coupling is an essential mechanism underlying quantum phenomena such as the spin Hall effect and topological insulators 1. It.

Ji, Fulde-Ferrell-Larkin-Ovchinnikov state to topologic superfluidity transition in bilayer spin-orbit coupled degenerate Fermi gas, Phys. Rev. A 95. No spin-orbit coupling is needed even when the scalar spin chirality vanishes, different from the case of the topological Hall effect and topological SHE reported previously. In known noncollinear antiferromagnetic compounds Mn3X (X = Ga, Ge, and Sn), for example, we indeed obtain large spin Hall conductivities based on ab initio calculations.

Dynamical phases in quenched spin–orbit-coupled.

The realization of spin-orbit coupling (SOC) in ultracold atoms has triggered an intensive exploring of topological superuids in the degenerate Fermi gases based on mean-eld theory, which has not yet been reported in experiments. Here, we demonstrate the topological phase transitions in the system via the numerically exact quantum Monte Carlo.

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. We would like to show you a description here but the site won’t allow us.

Hadzibabic Z., Yefsah T., Bakr W. S., Zwierlein M. W., Spin-injection spectroscopy of a spin-orbit coupled Fermi gas. Phys. Rev. Lett. 109, 095302 (2012. The origin of the effect is a crossing of bands (band inversion) induced by the 1T' phase which causes this material to satisfy the Kane-Mele criteria for creating a 2D topological insulator (Fig. 1b). This was predicted to lead to the formation of topologically-protected edge-states that exhibit spin velocity locking (Figs 1c, d). Coherently driven atomic gases inside optical cavities hold great promise for generating rich dynamics and exotic states of matter. It was shown recently that an exotic topological superradiant state exists in a two-component degenerate Fermi gas coupled to a cavity, where local order parameters coexist with global topological invariants. In this work, we characterize in detail various.
