The silent dark sector: a field-theory approach to unified dark fluids with vanishing speed of sound
Javier de Cruz Pérez, Darío Jaramillo-Garrido, Antonio L. Maroto +1
We introduce a novel class of field-theory models that provide a unified description of the dark sector as a single perfect fluid with vanishing sound speed. These models also admi…
Cosmological properties of black-hole hair in the linearly coupled scalar-Gauss-Bonnet theory
Dražen Glavan, Darío Jaramillo-Garrido
We investigate the superhorizon behavior of scalar hair sourced by black holes in de Sitter spacetime in the linearly coupled shift-symmetric scalar-Gauss-Bonnet theory. Working in…
K-nonizing
Jose Beltrán Jiménez, Teodor Borislavov Vasilev, Darío Jaramillo-Garrido +2
We unveil the dynamical equivalence of field theories with non-canonical kinetic terms and canonical theories with a volume element invariant under transverse diffeomorphisms. The…
Symmetry restoration for TDiff scalar fields
Darío Jaramillo-Garrido, Antonio L. Maroto, Prado Martín-Moruno
We explore the idea of restoring the full diffeomorphism (Diff) invariance in theories with only transverse diffeomorphisms (TDiff) by the introduction of additional fields. In par…
TDiff in the Dark: Gravity with a scalar field invariant under transverse diffeomorphisms
Darío Jaramillo-Garrido, Antonio L. Maroto, Prado Martín-Moruno
We reflect on the possibility of having a matter action that is invariant only under transverse diffeomorphisms. This possibility is particularly interesting for the dark sector, w…
