Recent progress on nonlinear properties of parity-time (PT)-symmetric systems is
comprehensively reviewed in this article. PT symmetry started out in non-Hermitian quantum …

This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

Supersolidity combines superfluid flow with long-range spatial periodicity of solids, two
properties that are often mutually exclusive. The original discussion of quantum crystals and …

Gauge fields are central in our modern understanding of physics at all scales. At the highest
energy scales known, the microscopic universe is governed by particles interacting with …

Spin–orbit coupling links a particle's velocity to its quantum-mechanical spin, and is
essential in numerous condensed matter phenomena, including topological insulators and …

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

When a neutral atom moves in a properly designed laser field, its center-of-mass motion
may mimic the dynamics of a charged particle in a magnetic field, with the emergence of a …

In this Letter, we report the first experimental realization and investigation of a spin-orbit
coupled Fermi gas. Both spin dephasing in spin dynamics and momentum distribution …

In this Letter, we present an experimental study of the collective dipole oscillation of a spin-
orbit coupled Bose-Einstein condensate in a harmonic trap. The dynamics of the center-of …

An effective spin-orbit coupling can be generated in a cold atom system by engineering
atom-light interactions. In this Letter we study spin-1/2 and spin-1 Bose-Einstein …
