Rotational states of an asymmetric vortex pair with mass imbalance in binary condensates
Alice Bellettini, Andrea Richaud, Vittorio Penna
We consider massive vortices in binary condensates, where the immiscibility condition entails the trapping of the minority component in the vortex cores of the majority component.…
Conformal maps and superfluid vortex dynamics on curved and bounded surfaces: the case of an elliptical boundary
Matteo Caldara, Andrea Richaud, Pietro Massignan +1
Recent advances in cold-atom platforms have made real-time dynamics accessible, renewing interest in the motion of superfluid vortices in two-dimensional domains. Here we show that…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
Relative dynamics of quantum vortices and massive cores in binary BECs
Alice Bellettini, Andrea Richaud, Vittorio Penna
We study the motion of superfluid vortices with filled massive cores. Previous point-vortex models already pointed out the impact of the core mass on the vortex dynamical propertie…
Making ghost vortices visible in two-component Bose-Einstein condensates
Andrii Chaika, Andrea Richaud, Alexander Yakimenko
Ghost vortices constitute an elusive class of topological excitations in quantum fluids since the relevant phase singularities fall within regions where the superfluid density is a…
Massive superfluid vortices and vortex necklaces on a planar annulus
Matteo Caldara, Andrea Richaud, Massimo Capone +1
We study a superfluid in a planar annulus hosting vortices with massive cores. An analytical point-vortex model shows that the massive vortices may perform radial oscillations on t…
