Quantum Reissner-Nordström geometry: singularity and Cauchy horizon
R. Casadio, A. Giusti, J. Ovalle
We present a quantum description of electrically charged spherically symmetric black holes given by coherent states of gravitons in which both the central singularity and the Cauch…
Analogies between logistic equation and relativistic cosmology
Steve Dussault, Valerio Faraoni, Andrea Giusti
We develop several formal analogies between the logistic equation and the spatially homogeneous and isotropic relativistic cosmology described by the Einstein-Friedmann equations.…
Thermodynamics of scalar-tensor gravity
Valerio Faraoni, Andrea Giusti
Previously, the Einstein equation has been described as an equation of state, general relativity as the equilibrium state of gravity, and gravity as a non-equilibrium…
Effective metric outside bootstrapped Newtonian sources
Roberto Casadio, Andrea Giusti, Iberê Kuntz +1
We determine the complete space-time metric from the bootstrapped Newtonian potential generated by a static spherically symmetric source in the surrounding vacuum. This metric cont…
Spherical inhomogeneous solutions of Einstein and scalar-tensor gravity: a map of the land
Valerio Faraoni, Andrea Giusti, Bardia H. Fahim
We review spherical and inhomogeneous analytic solutions of the field equations of Einstein and of scalar-tensor gravity, including Brans-Dicke theory, non-minimally (possibly conf…
Emmy's letter to Santa Claus (and a reply): Vaidya geometries and scalar fields with null gradients
Valerio Faraoni, Andrea Giusti, Bardia H. Fahim
Emmy, a child prodigy, writes a letter to Santa Claus asking for a Vaidya solution sourced by a massless scalar field with null gradient for Christmas. Santa writes back explaining…
