Direct and inverse cascades in turbulent Bose-Einstein condensate
When a Bose-Einstein condensate (BEC) is driven out of equilibrium, density waves interact non-linearly and trigger the emergence of …

Friction-enhanced lifetime of bundled quantum vortices
Experiments in the early 1980s have shown that a compact bundle of quantum vortex rings in superfluid helium remains coherent and …
