On the Mathematical Foundations of Gravitational Decoupling in General Relativity
Andrea Giusti
We study the algebraic and geometric structures of gravitational decoupling within a fixed class of globally static, spherically symmetric spacetimes with non-vanishing areal-radiu…
Thermal origin of the attractor-to-general-relativity in scalar-tensor gravity
Valerio Faraoni, Andrea Giusti
The convergence of scalar-tensor gravity to general relativity, or the departure from it, are described in a new analogy with heat dissipation in a viscous fluid. This new thermal…
Realisations of type III stress-energy tensors of the Hawking-Ellis classification in scalar-tensor gravity
Narayan Banerjee, Valerio Faraoni, Robert Vanderwee +1
The ``ugly duckling'' of the Segré-Plebański-Hawking-Ellis classification of stress-energy tensors is believed to be either impossible or extremely difficult to realise in Einstein…
First-order thermodynamics of scalar-tensor gravity
Serena Giardino, Andrea Giusti
The first-order thermodynamics of scalar-tensor theory is a novel approach that exploits the intriguing relationship between gravity and thermodynamics to better understand the spa…
Thermal stability of stealth and de Sitter spacetimes in scalar-tensor gravity
Serena Giardino, Andrea Giusti, Valerio Faraoni
Stealth solutions of scalar-tensor gravity and less-known de Sitter spaces that generalize them are analyzed regarding their possible role as thermal equilibria at non-zero tempera…
Is de Sitter space always excluded in semiclassical f(R) gravity?
Roberto Casadio, Andrea Giugno, Andrea Giusti +1
It is shown that the recent corpuscular description of gravity generically excludes de Sitter spacetime in any semiclassical version of f(R) gravity. A phantom phenomenology of the…
