We discuss the coherent atomic oscillations between two weakly coupled Bose-Einstein
condensates. The weak link is provided by a laser barrier in a (possibly asymmetric) double …

Interference of atomic de Broglie waves tunneling from a vertical array of macroscopically
populated traps has been observed. The traps were located in the antinodes of an optical …

Josephson weak links between samples of macroscopic quantum systems such as
superconductors, superfluids, and Bose-Einstein condensates provide a unique tool with …

We review the experimental realization of a single bosonic Josephson junction for ultracold
gases, which was made possible by the generation of a precisely controllable double-well …

We have measured the relative phase of two Bose-Einstein condensates using a time-
domain, separated-oscillatory-field condensate interferometer. A single two-photon coupling …

Nearly five decades have elapsed since the seminal 1966 paper of PW Anderson on the
flow of superfluid helium, He 4 at that time. Some of his “considerations”—the role of the …

We study the population dynamics of a Bose-Einstein condensate in a double-well potential
throughout the crossover from Josephson dynamics to hydrodynamics. At barriers higher …

We propose an experiment that would demonstrate the dc and ac Josephson effects in two
weakly linked Bose-Einstein condensates. We consider a time-dependent barrier, moving …

Superfluids and superconductors are the only states of condensed matter that can be
described by a single wavefunction, with a coherent quantum phase Φ. The mass flow in a …

Bose-Einstein condensates in a double-well trap, as well 3 H e− B baths connected by
micropores, have been shown to exhibit Josephson-like tunneling phenomena. Unlike the …
