Rapid cooling of the Cassiopeia A neutron star due to superfluid quantum criticality
Hao-Fu Zhu, Guo-Zhu Liu, Xufen Wu
The rapid cooling of the neutron star in Cassiopeia A is speculated to arise from an enhanced neutrino emission caused by the onset of -wave neutron superfluidity in the cor…

New solution to the hyperon puzzle of neutron stars: Quantum many-body effects
Hao-Fu Zhu, Guo-Zhu Liu, Xufen Wu +1
The hyperon puzzle refers to the challenge of reconciling the existence of hyperons in neutron star cores and the observed high masses of neutron stars. The recent discovery of PSR…

Superfluid quantum criticality and the thermal evolution of neutron stars
Hao-Fu Zhu, Guo-Zhu Liu, Jing-Rong Wang +1
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 tran…
