Do negative absolute temperatures matter physics and specifically Statistical Physics? We
provide evidence that we can certainly answer positively to this vexata quaestio. The great …

We study the motion of a superfluid vortex in condensates having different background
density profiles, ranging from parabolic to uniform. The resulting effective point-vortex model …

Glitches are sudden spin-up events that interrupt the gradual spin-down of rotating neutron
stars. They are believed to arise from the rapid unpinning of vortices in the neutron star inner …

We experimentally study the emergence of microcanonical equilibrium states in the turbulent
relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected …

We study the onset of dissipation in an atomic Josephson junction between Fermi
superfluids in the molecular Bose-Einstein condensation limit of strong attraction. Our …

Within the Gross-Pitaevskii theory, we study precursory pattern formations to the nucleation
of vortex dipoles in a two-dimensional Bose-Einstein condensate stirred by a Gaussian …

We consider a disk-shaped cold atom Bose-Einstein condensate with repulsive atom-atom
interactions within a circular trap, described by a two-dimensional time-dependent Gross …

We consider the inertial mass of a vortex in a superfluid. We obtain a vortex mass that is well
defined and is determined microscopically and self-consistently by the elementary excitation …

When a superfluid flows past an obstacle, quantized vortices can be created in the wake
above a certain critical velocity. In the experiment by Kwon et al.[Phys. Rev. A 91, 053615 …

We investigate the existence of self-trapped nonlinear waves with multiple phase
singularities. Working with the cubic-quintic nonlinear Schrödinger equation, we focus on …
