Pulsars, i.e. fast rotating neutron stars, exhibit an intriguing phenomenon known as “Glitches”. A glitch refers to a sudden increase of the star rotation frequency, which then eventually relaxes back to its slow-down value. The underlying mechanism governing such a behavior is a big open question in the community. A possible explanation is connected to the stochastic unpinning of quantized...

Neutron star cores could host various novel phases, ranging from a nucleonic superfluid phase to exotic high-baryon-density quantum chromodynamics (QCD) phases. Several observational signals have been discussed in the literature for such phase transitions. The current work points to a unique phenomenon, the Kibble–Zurek mechanism, in which a superfluid vortex network forms during a phase...

Observations of neutron stars have revealed a rapid changing in rotation velocity, known as a “Glitch” phenomenon. The glitching mechanism is thought to be related to neutron superfluidity inside neutron stars. In the inner crust region, neutrons are $^1S_0$ superfluid. While in the outer core, they behave as $^3P_2$ superfluid, which may form half-Integer vortices [1]. Vortices in different...
