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…
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…
Pulse waves in the viscoelastic Kelvin-Voigt model: a revisited approach
Juan Luis Gonzalez-Santander, Francesco Mainardi, Andrea Mentrelli
We calculate the mechanical response ) of an initially quiescent semi-infinite homogeneous medium to a pulse applied at the origin, and this is achieved within the framework…
Transient waves in linear dispersive media with dissipation: an approach based on the steepest descent path
Francesco Mainardi, Andrea Mentrelli, Juan Luis Gonza'les Santander
In the study of linear dispersive media it is of primary interest to gain knowledge of the impulse response of the material. The standard approach to compute the response involves…
On linear waves with memory in a Bessel-like medium
A. Giusti, I. Colombaro, A. Mentrelli
We discuss the propagation of harmonic and transient waves for systems governed by a wave equation with memory whose integral kernel involves ratios of modified Bessel functions of…
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…
