Description
I will review some key aspects of the physics of neutron star superfluidity
and superconductivity, which play an important role in the phenomena of
pulsar timing noise and rotational glitches. New results will be presented
from quantum mechanical Gross-Pitaevskii simulations of vortex avalanches
in a pinned, decelerating superfluid, which show the correlated nature of
vortex motion during glitches explicitly for the first time and provide a
robust
explanation of certain aspects of glitch statistics. Future gravitational
wave
experiments probing neutron star superfluidity and superconductivity
will be evaluated critically and related to fundamental open questions
concerning the physics of bulk nuclear matter.
