# Hypermagnetic gyrotropy, inflation and the baryon asymmetry of the Universe

@article{Giovannini2015HypermagneticGI, title={Hypermagnetic gyrotropy, inflation and the baryon asymmetry of the Universe}, author={Massimo Giovannini}, journal={Physical Review D}, year={2015}, volume={92}, pages={121301} }

We investigate the production of the hypermagnetic gyrotropy when the electric and magnetic gauge couplings evolve at different rates, as it happens in the relativistic theory of the van der Waals forces. If a pseudoscalar interaction breaks the duality symmetry of the corresponding equations, the gyrotropic configurations of the hypermagnetic fields can be amplified from the vacuum during an inflationary stage of expansion. After charting the parameter space of the model in terms of the rates…

We investigate the eﬀects of a large-scale background hypermagnetic ﬁeld on the electroweak phase transition. We propose a model in which an eﬀective weak angle varies during the electroweak phase…

Palatini approach and large-scale magnetogenesis

Large-scale magnetogenesis is analyzed within the Palatini approach when the gravitational action is supplemented by a contribution that is nonlinear in the Einstein-Hilbert term. While the addition…

A Pure Quantum Universe as an Alternative to Inflation

- PhysicsInternational Journal of Cosmology, Astronomy and Astrophysics

A model of the expansion of the universe is proposed, based on the assumption that the universe in its early stages was not in a hot state but in a pure, metastable quantum state. This assumption…
