_aGeneration of the magnetic helicity in a neutron star driven by the electroweak electron-nucleon interaction _cM. Dvornikov, V. B. Semikoz |
| 520 | 3 | _aWe study the instability of magnetic fields in a neutron star core driven by theparity violating part of the electron-nucleon interaction in the Standard Model. Assuming a seed field of the order 1012 G, that is a common value for pulsars, one obtains its amplification due to such a novel mechanism by about five orders of magnitude, up to 1017 G, at time scales ∼ (103–105) yr. This effect is suggested to be a possible explanation of the origin of the strongest magnetic fields observed in magnetars. The growth of a seed magnetic field energy density is stipulated by the corresponding growth of the magnetic helicity density due to the presence of the anomalous electric current in the Maxwell equation. Such an anomaly is the sum of the two competitive effects: (i) the chiral magnetic effect driven bythe difference of chemical potentials for the right and left handed massless electrons and (ii) constant chiral electroweak electron-nucleon interaction term, which has the polarization origin and depends on the constant neutron density in a neutron star core. The remarkable issue for the decisive role of the magnetic helicity evolution in the suggested mechanism is the arbitrariness of an initial magnetic helicity including the case of non-helical fields from the beginning. The tendency of the magnetic helicity density to the maximal helicity case at large evolution times | |
