The silent dark sector: a field-theory approach to unified dark fluids with vanishing speed of sound
Javier de Cruz Pérez, DarÃo 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 perturbations of TDiff fields
Antonio L. Maroto, Prado MartÃn-Moruno, Diego Tessainer
We study scalar field theories that break diffeomorphism invariance down to the subgroup of transverse diffeomorphisms through the matter sector in cosmological backgrounds. We foc…
Inflation in theories with broken diffeomorphisms
Antonio L. Maroto, Prado MartÃn-Moruno, Miguel Orbaneja-Pérez
We analyze the impact of breaking diffeomorphism invariance in the inflaton sector. In particular, we consider inflaton models which are invariant under the subgroup of transverse…
Multifield theories invariant under transverse diffeomorphisms: The mixed regime case
Antonio L. Maroto, Prado MartÃn-Moruno, Diego Tessainer
We study theories breaking diffeomorphism (Diff) invariance down to the subgroup of transverse diffeomorphisms (TDiff), consisting of multiple scalar fields in a cosmological backg…
CDM from broken diffeomorphisms
Javier de Cruz Pérez, Antonio L. Maroto
We present a simple field theory model with reduced invariance under diffeomorphisms whose energy-momentum tensor is identical to the sum of pressureless irrotational matter and a…
Multi-field TDiff theories for cosmology
Diego Tessainer, Antonio L. Maroto, Prado MartÃn-Moruno
We consider theories which break the invariance under diffeomorphisms (Diff) down to transverse diffeomorphisms (TDiff) in the matter sector, consisting of multiple scalar fields.…
