This review paper presents an overview of the theoretical and experimental progress on the
study of matter-wave dark solitons in atomic Bose–Einstein condensates. Upon introducing …

We report on the observation of controllable phase separation in a dual-species Bose-
Einstein condensate with Rb 85 and Rb 87. Interatomic interactions between the different …

The phenomenon of Bose–Einstein condensation is a phase transition originally predicted
by Bose and Einstein in 1924. In particular, it was shown that below a critical temperature T …

The dynamics of two penetrating superfluids exhibit an intriguing variety of nonlinear effects.
Using two distinguishable components of a Bose-Einstein condensate, we investigate the …

Understanding the behavior of quantized vortices is essential to gaining insight into diverse
superfluid phenomena, from critical-current densities in superconductors to quantum …

The aim of this review is to introduce the reader to some of the physical notions and the
mathematical methods that are relevant to the study of nonlinear waves in Bose–Einstein …

We use collective oscillations of a two-component Bose-Einstein condensate (2CBEC) of 87
Rb atoms prepared in the internal states| 1〉≡| F= 1, m F=− 1〉 and| 2〉≡| F= 2, m F= 1〉 for …

We investigate controlled phase separation of a binary Bose-Einstein condensate in the
proximity of a mixed-spin-channel Feshbach resonance in the| F= 1, m F=+ 1〉 and| F= 2, m …

Progress in understanding quantum systems has been driven by the exploration of the
geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom …

The miscibility of two interacting quantum systems is an important testing ground for the
understanding of complex quantum systems. Two-component Bose-Einstein condensates …
