Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

In this paper, we mainly review recent results on mathematical theory and numerical
methods for Bose-Einstein condensation (BEC), based on the Gross-Pitaevskii equation …

After reviewing the ideal Bose-Einstein gas in a box and in a harmonic trap, the effect of
interactions on the formation of a Bose-Einstein condensate are discussed, along with the …

Persistent currents in annular geometries have played an important role in disclosing the
quantum phase coherence of superconductors and mesoscopic electronic systems …

We analyze microparticle dynamics within a “perfect” vortex beam. In contrast to other vortex
fields, for any given integer value of the topological charge, a “perfect” vortex beam has the …

We have created a long-lived (<? format?>≈ 40 s) persistent current in a toroidal Bose-
Einstein condensate held in an all-optical trap. A repulsive optical barrier across one side of …

This book deals with applications in several areas of science and technology that make use
of light which carries orbital angular momentum. In most practical scenarios, the angular …

Some 16 years ago, Allen et al.[Phys. Rev. A 45, 8185 (1992)] recognised that laser beams
which carried an angular momentum additional to photon spin, could be realized in the …
