Mass-driven vortex collisions in flat superfluids

A Richaud, G Lamporesi, M Capone, A Recati - Physical Review A, 2023 - APS
Quantum vortices are often endowed with an effective inertial mass, due, for example, to
massive particles in their cores. Such “massive vortices” display new phenomena beyond …

Sound emission and annihilations in a programmable quantum vortex collider

WJ Kwon, G Del Pace, K Xhani, L Galantucci… - Nature, 2021 - nature.com
