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. Coupling the bosons to a fermionic species can further stabilize these phases. We estimate that the crystalline and quasicrystalline phases should be detectable in realistic…

Chiral Supersolid in Spin-Orbit-Coupled Bose Gases with Soft-Core Long-Range Interactions.
TLDR
It is demonstrated that the combined effects of spin-orbit coupling and interatomic soft-core long-range interaction can induce an exotic supersolid phase in which the chiral symmetry is broken with spontaneous emergence of circulating particle current.
Stable Dilute Supersolid of Two-Dimensional Dipolar Bosons.
TLDR
The three-body repulsion is crucial for stabilizing the system, and it is shown that the model allows for stable continuous space supersolid states in the dilute regime and the zero-temperature phase diagram.
Spin-orbit Coupling in Optical Lattices
In this review, we discuss the physics of spin-orbit coupled quantum gases in optical lattices. After reviewing some relevant experimental techniques, we introduce the basic theoretical model and

A long-lived spin-orbit-coupled degenerate dipolar Fermi gas
We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate atoms using the most magnetic fermionic element, dysprosium. Spin-orbit-coupling arises from a synthetic gauge
Supersolid with nontrivial topological spin textures in spin-orbit-coupled Bose gases
Supersolid is a long-sought exotic phase of matter, which is characterized by the coexistence of a diagonal long-range order of solid and an off-diagonal long-range order of superfluid. Possible

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.
Ground-state properties of spin–orbit-coupled dipolar Bose–Einstein condensates with in-plane gradient magnetic field
We investigate the ground-state properties of spin-orbit-coupled pseudo-spin-1/2 dipolar Bose-Einstein condensates (BECs) in a two-dimensional harmonic trap and an in-plane quadrupole field. The
Metallic state in bosonic systems with continuously degenerate dispersion minima
A continuously degenerate minima of the single particle dispersion is realized in the presence of an isotropic spin-orbit coupling above one dimension. The unit codimension of the dispersion-minima

TLDR
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
