	Production of Axions by Cosmic Magnetic Helicity (5 Apr 2006) by L. Campanelli, M. Giannotti posted to magnetic-fields helicity cosmology axion by lukasho on 2009-11-13 09:58:20 Abstract Copy My Attachments My Copy Abstract We investigate the effects of an external magnetic helicity production on the evolution of the cosmic axion field. It is shown that a helicity larger than (few × 10^-15 G)^2 Mpc, if produced at temperatures above a few GeV, is in contradiction with the existence of the axion, since it would produce too much of an axion relic abundance. ...
	Magnetic helicity generation from the cosmic axion field Phys. Rev., Vol. D72 (2005) by Leonardo Campanelli, M. Giannotti posted to axion cosmology generation helicity magnetic-fields seeds by lukasho on 2008-07-08 10:03:55 Abstract Copy My Attachments My Copy Abstract The coupling between a primordial magnetic field and the cosmic axion field generates a helical component of the magnetic field around the time in which the axion starts to oscillate. If the energy density of the seed magnetic field is comparable to the energy density of the universe at that time, then the resulting magnetic helicity is about \|H_B\| \∼eq (10^-20 G)^2 kpc and remains constant after its generation. As a corollary, we find that the standard properties of the oscillating ...
