The recent experimental realization of spin-orbit (SO) coupling for ultracold bosons and fermions opens an exciting avenue for engineering quantum matter that may be challenging to realize in solid state materials such as SO coupled spin-1 fermions. While one-dimensional SO coupling for spin-1 bosons has been experimentally realized, the generation of two-dimensional (2D) SO coupling and its.

Two-dimensional spin-orbit-coupled Fermi gases subject to s-wave pairing can be driven into a topological phase by increasing the Zeeman spin splitting beyond a critical value. In the topological regime, the system exhibits the hallmarks of chiral p-wave superfluidity, including exotic Majorana excitations.

Topological phases in pseudospin-1 Fermi gases with two.

We study the stability region of the topological superfluid phase in a trapped two-dimensional polarized Fermi gas with spin-orbit coupling and across a BCS-BEC crossover. Due to the competition between polarization, pairing interaction and spin-orbit coupling, the Fermi gas typically phase separates in the trap. Employing a mean field approach that guarantees the ground state solution, we. Disentangling Pauli Blocking of Atomic Decay from Cooperative Radiation and Atomic Motion in a 2D Fermi Gas. T.

And Green11, it is shown that a boundary between a 2D topological p+ ipsuperconducto and a trivial one hosts a single Majorana mode, and in a vortex core a Majo-rana bound state (MBS) is formed. A prime example of a system hosting MBS was introduced by Kitaev12. The model is a chain of spin-less fermions with superconduct-ing p-wave order.

Fulde-Ferrell-Larkin-Ovchinnikov Phases in Two-dimensional Spin-Orbit.

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 super uid. In the BCS limit of s-wave pairing, i.e., when Cooper pairs are only weakly bound, the system enters the topo. Jan 24, 2022 · Spin–orbit coupling is an essential mechanism underlying quantum phenomena such as the spin Hall effect and topological insulators 1. It has been widely studied in well-isolated Hermitian.

Superfluidity and collective modes in Rashba spin-orbit coupled Fermi gases.

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.
