Six-Field Rational Extended Thermodynamics of Polyatomic Gases in Curved Spacetime
Luca Gallerani, Andrea Giusti, Andrea Mentrelli +1
The paper develops a generally covariant six-field Rational Extended Thermodynamics model for relativistic polyatomic gases, couples it to Einstein’s equations, and studies its cos…

Towards a causal effective thermodynamics of scalar-tensor gravity
Narayan Banerjee, Andrea Giusti, Valerio Faraoni +2
The thermal analogy between the effective fluid of scalar-tensor gravity and Eckart's irreversible thermodynamics is extended to the causal Israel-Stewart model, adopting the minim…

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…
