How the Schwarzschild-de Sitter horizons remain in thermal equilibrium at vastly different temperatures
Marcello Miranda, Massimiliano Rinaldi, Valerio Faraoni
The Tolman-Ehrenfest criterion of thermal equilibrium for a static fluid in a static spacetime is generalized to stationary heat conduction, in the approximation in which backreact…
General analysis of Noether symmetries in Horndeski gravity
Marcello Miranda, Salvatore Capozziello, Daniele Vernieri
We explore Noether symmetries of Horndeski gravity, extending the classification of general scalar-tensor theories. Starting from the minimally coupled scalar field and the first-g…
Covariant single-field formulation of effective cosmological bounces
Marcello Miranda
This study explores the feasibility of an effective Friedmann equation in removing the classical Big Bang initial singularity and replacing it with a non-singular bounce occurring…
