- W2040881773 abstract "Recentlytorsion fields were introduced in CP-violating cosmic axion a2-dynamos[Garcia de Andrade, Mod Phys Lett A, (2011)] in order to obtain Lorentzviolating bounds for torsion. Here instead, oscillating axion solutions of thedynamo equation with torsion modes [Garcia de Andrade, Phys Lett B (2012)] areobtained taking into account dissipative torsion fields. Magnetic helicitytorsion oscillatory contribution is also obtained. Note that the torsion presenceguarantees dynamo efficiency when axion dynamo length is much stronger than thetorsion length. Primordial axion oscillations due to torsion yield a magneticfield of 109 G at Nucleosynthesis epoch. This is obtained due to adecay of BBN magnetic field of 1015 G induced by torsion. Sincetorsion is taken as 10–20 s–1, the dynamo efficiency isgranted over torsion damping. Of course dynamo efficiency is better in theabsence of torsion. In the particular case when the torsion is obtained fromanomalies it is given by the gradient of axion scalar [Duncan et al., Nuclear Phys B 87, 215] that asimpler dynamo equation is obtained and dynamo mechanism seems to be efficientwhen the torsion helicity, is negative while magnetic field decays when thetorsion is positive. In this case an extremely huge value for the magneticfield of 1015 Gauss is obtained. This is one order of magnitudegreater than the primordial magnetic fields of the domain wall. Actually if oneuses tDW ~ 10-4 s one obtains BDW ~ 1022 G which is amore stringent limit to the DW magnetic primordial field." @default.
