Our work focuses on decaying quantum turbulence in the vicinity of an anomalous non-thermal fixed point (NTFP) characterized by slow, subdiffusive coarsening of a length scale. The NTFP is approached in the temporal evolution of a quasi-2d dilute Bose gas starting from variously sampled initial vortex configurations. The universal dynamics is accompanied by the build-up of an inverse energy...

A neutron star is expected to contain a rotating neutron superfluid, threaded by 10^17 quantized vortices, in an environment with a much larger number of pinning sites. The interaction between these two entities, along with the spin-down of the star's crust, is thought to be the primary driver of pulsar glitches. Given reasonable computational resources, existing Gross-Pitaevskii simulations...

Neutron stars glitches, sudden spin-up events observed in their rotation, can be attributed to a transfer of angular momentum from an internal superfluid reservoir through a superfluid vortex-avalanche process. This research extends existing models by introducing new hypotheses in order to achieve a self-consistent description of superfluid vortex dynamics and avalanche probability....

Recent experimental realizations of ultracold atom bubble traps in microgravity conditions have triggered the exploration of quantum many-body physics in curved geometries, beyond the flat-space paradigm. We investigate a two-component Fermi gas on a spherical surface, analyzing how the interplay between curvature and interactions modifies its physical properties, both at finite and zero...

Bose-Einstein condensation is a ubiquitous phenomenon, present across a multitude of physical scales, from coherence among some thousands of atoms, to macroscopic superfluidity in liquid helium, up to theorised superfluid-superconducting neutrons and protons responsible for observed glitches in neutron stars. At all of these scales, questions persist around the subject of non-equilibrium...

We present an interactive 3D Particle-In-Cell (PIC) simulation of a global pulsar magnetosphere implemented in a browser-based HTML/WebGL environment. The model self-consistently evolves electromagnetic fields and relativistic plasma by solving Maxwell’s equations on a discretized grid (Yee scheme) coupled to particle dynamics via the Lorentz force. Charged particles are advanced using a...

The internal magnetic field configuration of neutron stars remains a key open problem in relativistic astrophysics, with significant implications for their evolution and electromagnetic and gravitational-wave emission. In our work, we investigated the stability of axisymmetric magnetic field configurations in a $n=1$ polytropic neutron star by combining the study of Configurational Entropy...
