Sound emission and annihilations in a programmable quantum vortex collider

WJ Kwon, G Del Pace, K Xhani, L Galantucci… - Nature, 2021 - nature.com
In quantum fluids, the quantization of circulation forbids the diffusion of a vortex swirling flow
seen in classical viscous fluids. Yet, accelerating quantum vortices may lose their energy …

Numerical studies of quantum turbulence

M Tsubota, K Fujimoto, S Yui - Journal of Low Temperature Physics, 2017 - Springer

Giant vortex clusters in a two-dimensional quantum fluid

G Gauthier, MT Reeves, X Yu, AS Bradley, MA Baker… - Science, 2019 - science.org
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 …

Prethermalization and universal dynamics in near-integrable quantum systems

T Langen, T Gasenzer… - Journal of Statistical …, 2016 - iopscience.iop.org
