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 …

We present a survey of some recent theoretical and experimental studies on nonlinear
waves that form and propagate in a broad class of optical and matterwave media. The article …

Dynamical quantum phase transitions are closely related to equilibrium quantum phase
transitions for ground states. Here, we report an experimental observation of a dynamical …

We present experimental and theoretical results on formation of quantum vortices in a laser
beam propagating in a nonlinear medium. Topological constrains richer than the mere …

The composite cosmological objects—Kibble-Lazarides-Shafi (KLS) walls bounded by
strings and cosmic strings terminated by Nambu monopoles—could be produced during the …

We find a novel topological defect in a spin-nematic superfluid theoretically. A quantized
vortex spontaneously breaks its axisymmetry, leading to an elliptic vortex in nematic-spin …

Among vortex structures identified so far in superfluid He 3-B, the most common are the A-
phase-core and double-core vortices. According to earlier numerical calculations, the …

The different superfluid phases of 3 He are described by p-wave order parameters that
include anisotropy axes both in the orbital and spin spaces. The anisotropy axes …

Excited-state quantum phase transitions depend on and reveal the structure of the whole
spectrum of many-body systems. While they are theoretically well understood, finding …

We provide an algorithm, i-SPin 2, for evolving general spin-s Gross-Pitaevskii or nonlinear
Schrödinger systems carrying a variety of interactions, where the 2 s+ 1 components of the …
