Radio pulsars provide us with some of the most stable clocks in the universe. Nevertheless
several pulsars exhibit sudden spin-up events, known as glitches. More than forty years after …

This review focuses on applications of the ideas of superfluidity and superconductivity in
neutron stars in a broader context, ranging from the microphysics of pairing in nucleonic …

Neutron stars are unique cosmic laboratories in which fundamental physics can be probed
in extreme conditions not accessible to terrestrial experiments. In particular, the precise …

ABSTRACT A region of toroidally oriented quantized flux lines must exist in the proton
superconductor in the core of the neutron star. This region will be a site of vortex pinning and …

Quantum mechanical simulations of neutron star rotational glitches, triggered by vortex
avalanches in the superfluid stellar interior, reveal that vortices pin nonaxisymmetrically to …

Timing of the Crab and Vela pulsars has recently revealed very peculiar evolutions of their
spin frequency during the early stage of a glitch. We show that these differences can be …

In a search for periodic variation in the arrival times of pulses from 151 young, energetic
pulsars, we have identified seven cases of modulation consistent with one or two harmonics …

Pulsar glitches are attributed to the sudden recoupling of weakly coupled superfluid
components in the neutron star interior. The transfer of angular momentum between the …

Abstract Three-dimensional, Gross-Pitaevskii equation (GPE) simulations are presented of
the interaction between neutron superfluid vortices and proton superconductor flux tubes in …

We demonstrate that observations of glitches in the Vela pulsar can be used to investigate
the strength of the crust–core coupling in a neutron star and provide a powerful probe of the …
