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 …

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

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 …

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 …

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 …

Chiral inorganic nanomaterials due to their unique asymmetric nanostructures have
gradually demonstrated intriguing chirality-dependent performance in photo (electro) …

Spin-orbit-coupled ultracold atoms provide an intriguing new avenue for the study of rich
spin dynamics in superfluids. In this Rapid Communication, we observe Zitterbewegung, the …

It is commonly known that two-dimensional mean-field models of optical and matter waves
with cubic self-attraction cannot produce stable solitons in free space because of the …

We study bright solitons in a Bose-Einstein condensate with a spin-orbit coupling that has
been realized experimentally. Both stationary bright solitons and moving bright solitons are …

Skyrmions are coreless vortex-like excitations emerging in diverse condensed-matter
systems, and real-time observation of their dynamics is still challenging. Here we report the …
