Irreversible Dynamics of Vortex Reconnections in Quantum Fluids
Irreversible Dynamics of Vortex Reconnections in Quantum Fluids
We statistically study vortex reconnections in quantum fluids by evolving different realizations of vortex Hopf links using the Gross--Pitaevskii model. Despite the time-reversibility of the model, we report a clear evidence that the dynamics of the reconnection process is time-irreversible, as reconnecting vortices tend to separate faster than they approach. …
