Effective fluid mixture of tensor-multi-scalar gravity
Marcello Miranda, Pierre-Antoine Graham, Valerio Faraoni
We apply to tensor-multi-scalar gravity the effective fluid analysis based on the representation of the gravitational scalar field as a dissipative effective fluid. This generaliza…

Critical solutions of nonminimally coupled scalar field theory and first-order thermodynamics of gravity
Valerio Faraoni, Pierre-Antoine Graham, Alexandre Leblanc
Analytical solutions of nonminimally coupled scalar field cosmology corresponding to critical scalar field values constitute a potential challenge to the recent first-order thermod…
