Thermomechanics of Horndeski Scalar Hair with Spacelike Gradients
Marcello Miranda, Marco Sebastianutti, Andrea Giusti
We develop a thermomechanical framework for viable Horndeski scalar hair with spacelike scalar-field gradients. Adapting the formalism to the scalar configuration, we…
Scalar field scattering in a Schwarzschild-de Sitter geometry
Marco de Cesare, Marcello Miranda, Achilleas P. Porfyriadis
We solve analytically the low-frequency s-wave dynamics of a massless scalar field propagating on a Schwarzschild-de Sitter black hole background. A rigorous application of the met…
Alternative formulations of the thermodynamics of scalar-tensor theories
Luca Gallerani, Marcello Miranda, Andrea Giusti +1
We explore alternative formulations of the analogy between viable Horndeski gravity and Eckart's first-order thermodynamics. We single out a class of identifications for the effect…
First-order thermodynamics of Horndeski cosmology
Marcello Miranda, Serena Giardino, Andrea Giusti +1
We delve into the first-order thermodynamics of Horndeski gravity, focusing on spatially flat, homogeneous, and isotropic cosmologies. Our exploration begins with a comprehensive r…
