TDiff-fuelled cosmic magnetic fields
Antonio L. Maroto, Alfredo D. Miravet
We explore the consequences of the breaking of diffeomorphism (Diff) invariance in the electromagnetic sector. We consider the breaking of Diff symmetry down to the subgroup of tra…
TDiff invariant gauge fields in cosmology
Antonio L. Maroto, Alfredo D. Miravet
We study the dynamics of Abelian gauge fields invariant under transverse diffeomorphisms (TDiff) in cosmological contexts. We show that in the geometric optics approximation, very…
Gravitational leptogenesis from metric perturbations
Antonio L. Maroto, Alfredo D. Miravet
In this work we make the observation that the gravitational leptogenesis mechanism can be implemented without invoking new axial couplings in the inflaton sector. We show that in t…
Vector dark radiation and gravitational-wave polarization
Alfredo D. Miravet, Antonio L. Maroto
We consider conformal vector models which could play the role of a cosmological dark radiation component. We analyse the propagation of gravitational waves in the presence of this…
The imprint of ultralight vector fields on gravitational wave propagation
Alfredo D. Miravet, Antonio L. Maroto
We study the effects of ultralight vector field (ULVF) dark matter on gravitational-wave propagation. We find that the coherent oscillations of the vector field induce an anisotrop…
