Generation of strong magnetic fields in a nascent neutron star accounting for the chiral magnetic effect

Abstract: We propose the mean field dynamo model for the generation of strongest magnetic fields, B " 10 15 G, in a neutron star (NS) accounting for the chiral magnetic effect (CME) driven by the shock in a supernova (SN) progenitor of that NS. The temperature jump at a narrow shock front, where an initial magnetic field existing in inflowing matter rises sharply, is the source of the CME that prevails significantly the erasure of the CME due to the spin-flip through Coulomb collisions in plasma. The growth of the magne… Show more

“…Meanwhile, the CVE has been regarded as also involving the gravitational anomaly [7][8][9]. As observable manifestations of the quantum anomaly and topological properties of chiral gauge theories, chiral transport phenomena have been studied with immense efforts in various physical contexts, e.g., quark-gluon plasma in heavy-ion collisions [10][11][12][13][14][15]; topological condensed matter systems such as topological insulators [16][17][18][19][20][21] or Dirac and Weyl semimetals [22][23][24][25][26][27]; electroweak media in neutron stars [28][29][30][31][32], the primordial universe [33][34][35], or core-collapse supernovae [36][37][38].…”

“…Chiral MHD has also been applied to high energy astrophysical plasmas like the early Universe [24][25][26]39] and proto-neutron stars [40][41][42][43][44][45] where, in particular, the evolution of the magnetic field has been studied. Beyond that, chiral MHD can be used to describe the dynamics of new materials, like Weyl and Dirac semimetals [46].…”

“…However, the effects of the chiral vorticity and the viscosity have not been taken into account. In another work related to the evolution of the magnetic fields in the neutron stars, the authors have taken the chiral magnetic effect into account, while considering the axial number density as a time and space dependent variable [62]. Then, they have added a new pseudoscalar 1 The forms of these currents are different in the symmetric phase, and will be presented later.…”
