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 …

Mutual friction caused by scattering of thermal excitations by quantized vortices is a
phenomenon of key importance for the understanding of vortex dynamics and quantum …

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 …

A quantized vortex dipole is the simplest vortex molecule, comprising two countercirculating
vortex lines in a superfluid. Although vortex dipoles are endemic in two-dimensional …

We present a systematic theoretical analysis of the motion of a pair of straight counter-
rotating vortex lines within a trapped Bose–Einstein condensate. We introduce the …

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 …

We study computationally dynamics of quantized vortices in two-dimensional superfluid
Bose-Einstein condensates confined in highly oblate power-law traps. We have found that …

Multicomponent Bose-Einstein condensates exhibit an intriguing variety of nonlinear
structures. In recent theoretical work [C. Qu, LP Pitaevskii, and S. Stringari, Phys. Rev. Lett …
