There have been significant recent advances in realizing band structures with geometrical
and topological features in experiments on cold atomic gases. This review summarizes …

We demonstrate coupling between the atomic spin-and orbital-angular momentum (OAM) of
the atom's center-of-mass motion in a Bose-Einstein condensate (BEC). The coupling is …

Neutral particles subject to artificial gauge potentials can behave as charged particles in
magnetic fields. This fascinating premise has led to demonstrations of one-way waveguides …

Previous realizations of synthetic gauge fields for ultracold atoms do not allow the spatial
profile of the field to evolve freely. We propose a scheme which overcomes this restriction by …

We observed a new mechanism for vortex nucleation in Bose–Einstein condensates (BECs)
subject to synthetic magnetic fields. We made use of a strong synthetic magnetic field initially …

The implementation of static artificial magnetic fields in ultracold atomic systems has
become a powerful tool, eg for simulating quantum-Hall physics with charge-neutral atoms …

The notions of a topological phase and topological order were first introduced in the studies
of integer and fractional quantum Hall effects, and further developed in the study of …

Fast creation of a single vortex in BEC of alkali-metal atoms at a prescribed position and
time is still challenging, even though various methods to create single and multiple vortices …

Vortex lattices in rapidly rotating Bose-Einstein condensates are systems of topological
excitations that arrange themselves into periodic patterns. Here we show how phase …

Gauge fields are ubiquitous in modern quantum physics. In superfluids, quantized vortices
can be induced by gauge fields. Here we demonstrate the first experimental observation of …
