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

22 Jan 2020 Dvornikov Maxim 1 and 2 Semikoz V. B. Sokoloff D. D.

We propose the mean field dynamo model for the generation of strongest magnetic fields, $B\sim 10^{15}\,{\rm G}$, 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...
