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 …

We review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

We demonstrate that a Weyl point, widely examined in 3D Weyl semimetals and superfluids,
can develop a pair of nondegenerate gapless spheres. Such a bouquet of two spheres is …

Symmetry plays a fundamental role in understanding complex quantum matter, particularly
in classifying topological quantum phases, which have attracted great interests in the recent …

The recent experimental realization of synthetic spin-orbit coupling (SOC) opens a new
avenue for exploring novel quantum states with ultracold atoms. However, in experiments for …

Pairing in an attractively interacting two-component Fermi gas in the absence of time-
reversal symmetry or inversion symmetry may give rise to exotic superfluid states. Notable …

The electromagnetic spectrum between microwave and infrared light is termed the “terahertz
(THz) gap,” of which there is an urgent lack of feasible and efficient room‐temperature (RT) …

We report the realization of a robust and highly controllable two-dimensional (2D) spin-orbit
(SO) coupling with a topological nontrivial band structure. By applying a retro-reflected 2D …

In analogy to conventional semiconductor diodes, the Josephson diode exhibits
superconducting properties that are asymmetric in applied bias. The effect has been …

The recent experimental realization of spin-orbit (SO) coupling for spin-1 ultracold atoms
opens an interesting avenue for exploring SO-coupling-related physics in large-spin …
