No Primordial Magnetic Field from Domain Walls
It is pointed out that, contrary to some claims in the literature, the domain walls cannot be a source of a correlated at large scales primordial magnetic field, even if the fermionic modes bound on the wall had ferromagnetic properties. In a particular model with massive (2+1) dimensional fermions bound to a domain wall, previously claimed to exhibit a ferromagnetic behavior, it is explicitly ...
متن کاملNo Primordial Magnetic Field from Domain Walls ”
We comment on the recent preprint hep-ph/0007123 by M.B. Voloshin, claiming that domain walls are diamagnetic. We show that the results presented therein are based on an incorrect treatment of the zero mode contribution to the vacuum energy density. We also shown that the correct treatment leads to the conclusion that domain walls are ferromagnetic, and can generate a primordial magnetic field.
متن کاملOn the Primordial Magnetic Field from Domain Walls
In this paper we discuss once more the zero mode contribution to the vacuum energy density. We show that a careful treatment of the zero modes leads to the conclusion that domain walls may be ferromagnetic, and could generate a magnetic field of cosmological interest. Electronic address: [email protected] Electronic address: [email protected] In Ref. [1] we suggested that the spontaneous ge...
متن کاملDark energy from primordial inflationary quantum fluctuations.
We show that current cosmic acceleration can be explained by an almost massless scalar field experiencing quantum fluctuations during primordial inflation. Provided its mass does not exceed the Hubble parameter today, this field has been frozen during the cosmological ages to start dominating the Universe only recently. By using supernovae data, completed with baryonic acoustic oscillations fro...
متن کاملBaryogenesis from a Primordial Lepton Asymmetry
Abstract We examine the generation of baryon asymmetry at the weak scale from a primordial lepton asymmetry. If the electroweak phase transition is first order, partial reflection of tau leptons off the bubble walls and the resulting hypercharge transport into the symmetric phase, gives rise to a baryon number consistent with observation.We examine the generation of baryon asymmetry at the weak...
