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…
New interpretation of the Minkowski limit of gravity
Valerio Faraoni, Luca Gallerani, Alain Maltais-Gosselin +2
It is well-established that the Minkowski limit of pure gravity breaks down, unlike that of full Starobinsky theory . We provide a novel interpretation of…
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…
Quantum dust cores of black holes and their quasi-normal modes
Tommaso Bambagiotti, Luca Gallerani, Andrea Mentrelli +2
The quantum description of a gravitationally collapsed ball of dust proposed in Ref.~\cite{Casadio:2023ymt} is characterised by a linear effective Misner-Sharp-Hernandez mass funct…
Thermal aspects of the anomalous limit of Brans-Dicke gravity
L. Gallerani, A. Giusti, A. Mentrelli +1
Brans-Dicke gravity does not always reduce to General Relativity in the limit for the coupling constant. This anomalous behavior is examined within the formalism of t…
Mass (re)distribution for quantum dust cores of black holes
L. Gallerani, A. Mentrelli, A. Giusti +1
The collective ground state for a spherical symmetric dust ball has been investigated recently in [R. Casadio, Phys. Lett. B 843 (2023) 138055]. In this study, we refine that model…
