Magnetic field evolution in neutron star crusts: Beyond the hall effect

KN Gourgouliatos, D De Grandis, A Igoshev - Symmetry, 2022 - mdpi.com
Neutron stars host the strongest magnetic fields that we know of in the Universe. Their
magnetic fields are the main means of generating their radiation, either magnetospheric or …

Quarkyonic matter and quarkyonic stars in an extended relativistic mean field model

CJ Xia, HM Jin, TT Sun - Physical Review D, 2023 - APS
By combining relativistic mean field models and equivparticle models with density-
dependent quark masses, we construct explicitly “a quark Fermi sea” and “a baryonic Fermi …
