My lab has begun a superfluid helium experiment designed to exhibit glitch behavior, modeled after the Tsakadze and Tsakadze experiment from the 1970's. We levitate a bucket of helium, rotate the bucket, and let the bucket slow down while monitoring its angular velocity. We do observe glitches in which the angular velocity increases. I will discuss various effects that currently limit the...

The thermodynamic properties of a system of interacting relativistic bosonic particles and antiparticles at high temperatures and densities, in the presence of the Bose-Einstein condensate, are studied. The density functional mean-field model and the scalar field model were used to calculate phase diagrams and thermodynamic quantities for different ratios of attractive to repulsive forces in...

20. Reproducible nucleation and control of stable quantum vortex rings in Bose-Einstein condensates

Understanding vortex dynamics in three-dimensional superfluid systems emerges as a key challenge. Driven by the ultracold quantum gases laboratory that has recently been established in Milan, I will present a work [1] aimed at numerically investigating and controlling three-dimensional vortex ring formation and dynamics in trapped Bose-Einstein condensates.
In this work, we propose and...
