Out-of-equilibrium phenomena are a subject of considerable interest in many fields of
physics. Ultracold quantum gases, which are extremely clean, well-isolated and highly …

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 …

The crossing of a continuous phase transition gives rise to the formation of topological
defects described by the Kibble-Zurek mechanism (KZM) in the limit of slow quenches. The …

The spontaneous transformations associated with symmetry-breaking phase transitions
generate domain structures and defects that may be topological in nature. The formation of …

Quantized vortices are the hallmark of superfluidity, and are often sought out as the first
observable feature in new superfluid systems. Following the recent experimental …

We investigate the saturation of defect density in an atomic Bose gas rapidly cooled into a
superfluid phase. The number of quantum vortices, which are spontaneously created in the …

Abstract The Kibble–Zurek mechanism describes the spontaneous formation of topological
defects in a system crossing a continuous phase transition,. Its central premise is the notion …

We study the vortex nucleation dynamics in inhomogeneous atomic Bose gases quenched
into a superfluid phase and investigate the dependence of the Kibble-Zurek (KZ) scaling …

The emergence of macroscopic coherence in a many-body quantum system is a ubiquitous
phenomenon across different physical systems and scales. This Chapter reviews key …

Controlled quantum systems such as ultracold atoms can provide powerful platforms to
study nonequilibrium dynamics of closed many-body quantum systems, especially since a …
