We study the ground-state phases, the stability phase diagram and collapse dynamics of BoseEinstein condensates BECs with tunable spinorbit SO coupling in the two-dimensional harmonic potential by variational analysis and numerical simulation. Here we propose the theory that the collapse stability and collapse dynamics of BECs in the external trapping potential can be manipulated by.

Spin-Orbit Coupled Fermi Gases across a.... The particle and spin transport through a quantum point contact between two Fermi gases with Raman-induced spin-orbit coupling are investigated. We show that the particle and spin conductances both demonstrate the structure of plateau due to the mesoscopic scale of the quantum point contact. Feb 18, 2022 Abstract. Dark solitons in quantum fluids are well-known nonlinear excitations that are usually characterized by a single length scale associated with the underlying background fluid. We show that in the presence of spin-orbit coupling and a linear Zeeman field, superfluid Fermi gases support two different types of nonlinear excitations. Nov 04, 2011 In this Letter we study both ground state properties and the superfluid transition temperature of a spin-1/2 Fermi gas across a Feshbach resonance with a synthetic spin-orbit coupling, using the mean-field theory and the exact solution of two-body problem. We show that a strong spin-orbit coupling c.

We directly reveal the spin-orbit gap via spin-injection spectroscopy, which characterizes the energy-momentum dispersion and spin composition of the quantum states. For energies within the spin-orbit gap, the system. 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.
Dynamical phases in quenched spin-orbit-coupled degenerate Fermi gas.
In this paper, we investigate the phase diagram of the interacting Fermi gas with Rashba-type SOC on a square optical lattice. Such a system can be described by the spinorbit SO coupled fermionic Hubbard model, see equation. We show that the SOC has important implications on the properties of MIT and phase diagram of this system.

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].
