Neutron stars are a fantastic cosmic laboratory where we can probe the high density regime of the fundamental interactions. In particular one of the most fascinating aspects of neutron star physics is that their interiors are cold: neutrons are expected to be superfluid and protons superconducting. This is not only well established on a theoretical basis, but superfluidity is thought to be at the heart of observable astronomical phenomena known as pulsar glitches: sudden spin-up events observed in hundreds of pulsars. Although these events were observed in pulsars soon after their discovery, a detailed understanding of the physical mechanism is still lacking. In this talk I will discuss recent advances, both theoretical and observational, and discuss the microphysics that can be constrained by modelling these events.
