When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic …

Nov 6, 2025 · In this paper, we consider the relativistic stars described by the non-transfusive superconducting- superfluid mixtures.

Aug 13, 2025 · The neutron star starts to cool down shortly after its birth by emitting neutrinos. As it becomes cold enough, the Cooper pairs of neutrons are formed, triggering a superfluid transition.

Neutron-star superfluidity was predicted by Arkady Migdal in 1959, and first studied by Ginzburg & Kirzhnits in 1964 before the discovery of pulsars in 1967. The huge gravity of neutron stars produces …

Sep 12, 2017 · Neutron stars, the compact stellar remnants of core-collapse supernova explosions, are unique cosmic laboratories for exploring novel phases of matter under extreme conditions. In …

Apr 22, 2024 · Meanwhile, the star's fluid core encompasses a combination of superfluid and superconductor materials. The star's behavior is significantly influenced by the characteristics linked …

This brief survey is intended to serve an introduction to dynamical aspects that come into play when we consider a superfluid neutron star.

Feb 24, 2011 · Two independent research teams have used data from NASA’s Chandra X-ray Observatory to show that the interior of a neutron star contains superfluid and superconducting …

Feb 22, 2011 · Superfluidity is one of the most striking macroscopic manifestations of quantum mechanics. Nucleons are fermions, and due to the Pauli exclusion principle, they generally tend to …

Feb 15, 2022 · In particular, neutron stars are the only celestial bodies that are expected to be superfluids and superconducting. Although quantum condensates have been extensively studied in …
