We explore the influence of contact interactions on a synthetically spin–orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show that a regime exists in which the competition between the contact and spin–orbit interactions results in the emergence of a ground state that contains a significant contribution from the anti-symmetric spin state. This ground state is unique to few-particle systems and does not exist in the mean-field regime. The…

Spin–orbit-coupled Bose–Einstein condensates

The engineered SO coupling in a neutral atomic Bose–Einstein condensate sets the stage for the realization of topological insulators in fermionic neutral atom systems and develops a many-body theory that provides quantitative agreement with the observed location of the transition.

Spin-orbit-coupled bosons interacting in a two-dimensional harmonic trap

A system of bosons in a two-dimensional harmonic trap in the presence of Rashba-type spin-orbit coupling is investigated. An analytic treatment of the ground state of a single atom in the

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.

Spin and field squeezing in a spin-orbit coupled Bose-Einstein condensate

This report investigates spin and field squeezing of the ground state in spin-orbit coupled Bose-Einstein condensate and finds that the presence of the detuning enhances the occupation number of harmonic trap mode, while it suppresses the spin and the field squeezing.

Properties of spin–orbit-coupled Bose–Einstein condensates

The experimental and theoretical research of spin–orbit-coupled ultracold atomic gases has advanced and expanded rapidly in recent years. Here, we review some of the progress that either was

Mean-field dynamics of spin-orbit coupled Bose-Einstein condensates.

A generic Gross-Pitaevskii equation is derived as the starting point for the study of many-body dynamics in spin-orbit coupled Bose-Einstein condensates and a new oscillation period induced by the SOC, similar to the Zitterbewegung oscillation, is found in the center-of-mass motion of the condensate.

Spin-injection spectroscopy of a spin-orbit coupled Fermi gas.

The coupling of the spin of electrons to their motional state lies at the heart of recently discovered topological phases of matter and the spin-orbit gap is revealed via spin-injection spectroscopy, which characterizes the energy-momentum dispersion and spin composition of the quantum states.

Degenerate Quantum Gases with Spin-Orbit Coupling

This review focuses on recent developments on synthetic spin-orbit (SO) coupling in ultracold atomic gases. Two types of SO coupling are discussed. One is Raman process induced coupling between spin

Quantum tricriticality and phase transitions in spin-orbit coupled Bose-Einstein condensates.

A spin-orbit coupled configuration of spin-1/2 interacting bosons with equal Rashba and Dresselhaus couplings is considered with special emphasis on the role of the interaction treated in the mean-field approximation.

Dicke-type phase transition in a spin-orbit-coupled Bose-Einstein condensate.

The ground state properties of a spin-orbit-coupled Bose-Einstein condensates system can be mapped to the well-known Dicke model in quantum optics, which describes the interactions between an ensemble of atoms and an optical field.
