Knots and links have been conjectured to play a fundamental role in a wide range of
physical fields, including plasmas and fluids, both quantum and classical. In fluids, the …

Linking, or multicomponent topological entanglement, is ubiquitous in soft matter systems,
from mixtures of polymers and DNA filaments packed in vivo to interlocked line defects in …

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 …

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 …

Knots and links often occur in physical systems, including shaken strands of rope and DNA
(ref.), as well as the more subtle structure of vortices in fluids and magnetic fields in plasmas …

The conjecture that helicity (or knottedness) is a fundamental conserved quantity has a rich
history in fluid mechanics, but the nature of this conservation in the presence of dissipation …

Vortices arise in many natural phenomena as dark points of total destructive interference.
Sometimes they form continuous lines and even enclosed loops with knotted or linked …

After more than a decade of experiments generating and studying the physics of quantized
vortices in atomic gas Bose–Einstein condensates, research is beginning to focus on the …

We report on the static and dynamical properties of multiple dark-antidark solitons (DADs) in
two-component, repulsively interacting Bose-Einstein condensates. Motivated by …

Polymers are an effective test bed for studying topological constraints in condensed matter
due to a wide array of synthetically available chain topologies. When linear and ring …
