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…

Six-Field Rational Extended Thermodynamics of Polyatomic Gases in Curved Spacetime
Luca Gallerani, Andrea Giusti, Andrea Mentrelli +1
We formulate a generally covariant six-field Rational Extended Thermodynamics model (RET) for relativistic polyatomic gases, with the dynamical pressure as the only non-equilib…

Revisiting induced gravity in scalar-tensor thermodynamics
Andrea Giusti
Induced gravity, defined as a globally scale-invariant ``first-generation'' scalar-tensor theory, is investigated within the framework of the thermodynamics of modified gravity the…
