Spectator Higgs field, large-scale gauge fields, and the nonminimal coupling to gravity

  title={Spectator Higgs field, large-scale gauge fields, and the nonminimal coupling to gravity},
  author={Massimo Giovannini},
  journal={Physical Review D},
Even if the Higgs field does not affect the evolution of the background geometry, its massive inhomogeneities induce large-scale gauge fields whose energy density depends on the slow-roll parameters, on the effective scalar mass and, last but not least, on the dimensionless coupling to the space-time curvature. Since the non-Abelian gauge modes are screened, the non-minimal coupling to gravity predominantly affects the evolution of the hypercharge and electromagnetic fields. While in the case…

Effective horizons, junction conditions and large-scale magnetism
The quantum mechanical generation of hypermagnetic and hyperlectric fields in four-dimensional conformally flat background geometries rests on the simultaneous continuity of the effective horizon and
Spectator electric fields, de Sitter spacetime, and the Schwinger effect
During a de Sitter stage of expansion the spectator fields of different spin are constrained by the critical density bound and by further requirements determined by their specific physical nature.


Graviton Creation by Small Scale Factor Oscillations in an Expanding Universe
We treat quantum creation of gravitons by small scale factor oscillations around the average of an expanding universe. Such oscillations are predicted both by modied gravity theories with a term
