The experimental realisation of Bose–Einstein condensates of dilute atomic vapours has
generated immense interest and activity in this field. Here, we present a review of recent …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

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 …

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

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 …

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 …

We propose a scheme to create a macroscopic “Schrödinger-cat” state formed by two
interacting Bose condensates. In analogy with quantum optics, where the control and …

We obtain analytic solutions to the Gross-Pitaevskii equation with negative scattering length
in highly asymmetric traps. We find that in these traps the Bose-Einstein condensates …

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 revisit a classic study [DS Hall, Phys. Rev. Lett. 81, 1539 (1998) PRLTAO 0031-9007
10.1103/PhysRevLett. 81.1539] of interpenetrating Bose-Einstein condensates in the …
