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 term “quantum turbulence”(QT) unifies the wide class of phenomena where the chaotic
set of one dimensional quantized vortex filaments (vortex tangles) appear in quantum fluids …

Turbulent phenomena are among the most striking effects that both classical and quantum
fluids can exhibit. Although classical turbulence is ubiquitous in nature, the observation of …

Adding energy to a system through transient stirring usually leads to more disorder. In
contrast, point-like vortices in a bounded two-dimensional fluid are predicted to reorder …

A central concept in the modern understanding of turbulence is the existence of cascades of
excitations from large to small length scales, or vice versa. This concept was introduced in …

Nonequilibrium interacting systems can evolve to exhibit large-scale structure and order. In
two-dimensional turbulent flow, the seemingly random swirling motion of a fluid can evolve …

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 …

Quantized vortices appear in quantum gases at the breakdown of superfluidity. In liquid
helium and cold atomic gases, they have been indentified as the quantum counterpart of …

This book introduces the theoretical description and properties of quantum fluids. The focus
is on gaseous atomic Bose–Einstein condensates and, to a minor extent, superfluid helium …
