Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many
physical systems across various disciplines, from tiny laboratory scales to geophysical and …

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 …

The aim of this introductory article is two-fold. First, we aim to offer a general introduction to
the theme of Bose-Einstein condensates, and briefly discuss the evolution of a number of …

Reconnections and interactions of filamentary coherent structures play a fundamental role in
the dynamics of fluids, redistributing energy and helicity among the length scales and …

During the past decade there has been an increased interest in the study of localized
structures in optics and in the area of matter waves [atomic Bose-Einstein condensates …

We study the dynamics of small vortex clusters with a few (2–4) corotating vortices in Bose-
Einstein condensates by means of experiments, numerical computations, and theoretical …

This special issue grew out of a BIRS workshop of the same title that was held in February
2012. It contains new research contributions from a broad spectrum of researchers on topics …

Deformation flows are the flows incorporating shear, strain and rotational components.
These flows are ubiquitous in the geophysical flows, such as the ocean and atmosphere …

We derive a general and exact equation of motion for a quantized vortex in an
inhomogeneous two-dimensional Bose-Einstein condensate. This equation expresses the …

Quantum vortices, the quantized version of classical vortices, play a prominent role in
superfluid and superconductor phase transitions. However, their exploration at a particle …
