Turbulent relaxation to equilibrium in a two-dimensional quantum vortex gas
Matthew T. Reeves, Kwan Goddard-Lee, Guillaume Gauthier +9
We experimentally study emergence of microcanonical equilibrium states in the turbulent relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected…
Vortex Nucleation Limited Mobility of Free Electron Bubbles in the Gross-Pitaevskii Model of a Superfluid
Alberto Villois, Hayder Salman
We study the motion of an electron bubble in the zero temperature limit where neither phonons nor rotons provide a significant contribution to the drag exerted on an ion moving wit…
Wind generated rogue waves in an annular wave flume
A. Toffoli, D. Proment, H. Salman +7
We investigate experimentally the statistical properties of a wind-generated wave field and the spontaneous formation of rogue waves in an annular flume. Unlike many experiments on…
Long-range Ordering of Topological Excitations in a Two-Dimensional Superfluid Far From Equilibrium
Hayder Salman, Davide Maestrini
We study the relaxation of a 2D ultracold Bose-gas from a nonequilibrium initial state containing vortex excitations in experimentally realizable square and rectangular traps. We s…
A Vortex Filament Tracking Method for the Gross-Pitaevskii Model of a Superfluid
Alberto Villois, Giorgio Krstulovic, Davide Proment +1
We present an accurate and robust numerical method to track quantized vortex lines in a superfluid described by the Gross-Pitaevskii equation. By utilizing the pseudo-vorticity fie…
