Descrizione

Title
Exploring pulsar glitches with supersolids

Abstract
Glitches, spin-up events in neutron stars, are of prime interest as they reveal properties of nuclear matter at subnuclear densities. We explore a possible glitch mechanism due to vortex unpinning using analogies between neutron stars and dipolar supersolids. We numerically observe the vortex and crystal dynamics during a glitch and its dependence on the supersolid quality, providing a tool to study glitches from different radial depths of a neutron star. Our work paves the way for the quantum simulation of stellar objects from Earth.
