This article summarizes some of the relevant features exhibited by binary mixtures of Bose–
Einstein condensates in the presence of coherent coupling at zero temperature. The …

Despite ground-breaking observations of supersolidity in spin-orbit-coupled Bose-Einstein
condensates, until now the dynamics of the emerging spatially periodic density modulations …

We briefly review the recent progress of theories and experiments on spin-orbital-angular-
momentum (SOAM)-coupled quantum gases. The coupling between the intrinsic degree of …

We investigate the superfluid fraction of crystalline stationary states within the framework of
mean-field Gross–Pitaevskii theory. Our primary focus is on a two-dimensional Bose …

While a spin–orbit-coupled spin-1 Bose–Einstein condensate (BEC) has been
experimentally observed, its elementary excitations remain unclear in the stripe phase …

Supersolidity is deeply connected with the emergence of Goldstone modes, reflecting the
spontaneous breaking of both phase and translational symmetry. Here, we propose …

The phase diagram of a Bose-Einstein condensate with Raman-induced spin-orbit coupling
includes a stripe phase with supersolid features. In this work we develop a perturbation …

Supersolid is a special state of matter with both superfluid properties and spontaneous
modulation of particle density. In this paper we focus on the supersolid stripe phase realized …

We propose a spin-orbit-coupled Floquet spinor Bose-Einstein condensate (BEC) which can
be implemented by Floquet engineering of a quadratic Zeeman field. The Floquet spinor …

One of brilliant achievements in spin-orbit-coupled Bose-Einstein condensates is the
discovery and observation of the supersolid stripe states. So far, all studied supersolid stripe …
