Abstract The phenomenon of Bose-Einstein condensation of dilute gases in traps is
reviewed from a theoretical perspective. Mean-field theory provides a framework to …

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 …

Bose–Einstein condensates—a low-temperature form of matter in which a macroscopic
population of bosons occupies the quantum-mechanical ground state—have been …

We describe the first experiments that study in a controlled way the dynamics of
distinguishable and interpenetrating bosonic quantum fluids. We work with a two-component …

The realization of Bose-Einstein condensation (BEe) in dilute atomic gases [1-5] achieved
several long-standing goals. First, neutral atoms were cooled into the lowest energy state …

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 …

We distinguish two types of spatial separation exhibited by atomic trap Bose-Einstein
condensates: potential separation, in which case the condensates diffuse into each other as …

We produce a quantum degenerate mixture composed by two Bose-Einstein condensates of
different atomic species, K 41 and R 87 b. We study the dynamics of the superfluid system in …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

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 …
