Semi-classical spacetime thermodynamics
Ana Alonso-Serrano, Marek Liška, MichaŠPiotrak
We derive the semi-classical gravitational dynamics from thermodynamics of local stretched light cones in 2-dimensional dilaton gravity, explicitly treating the backreaction of qua…
Gravity from equilibrium thermodynamics of stretched light cones
Ana Alonso-Serrano, Luis J. Garay, Marek Liška +1
This work digs into the connection between gravity and thermodynamics of stretched light cones (SLC). They are associated with uniformly accelerating observers, who endow the SLC w…
Quantum estimation of cosmological parameters
MichaÅ Piotrak, Thomas Colas, Ana Alonso-Serrano +1
Understanding how well future cosmological experiments can reconstruct the mechanism that generated primordial inhomogeneities is key to assessing the extent to which cosmology can…
Equivalence principles in Weyl transverse gravity
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
There exist two consistent theories of massless, self-interacting gravitons, which differ by their local symmetries: general relativity and Weyl transverse gravity. We show that th…
Black hole solutions in quantum phenomenological gravitational dynamics
Ana Alonso-Serrano, Marco de Cesare, Manuel Del Piano
We investigate black hole solutions within a phenomenological approach to quantum gravity based on spacetime thermodynamics developed by Alonso-Serrano and LiÅ¡ka. The field equati…
Black hole thermodynamics probes the equivalence principle
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
The equivalence principle for test gravitational physics strongly constrains dynamics of spacetime, providing a powerful criterion for selecting candidate theories of gravity. Howe…
