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…
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…
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 Liška. The field equatio…
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…
Gravity from thermodynamics in vacuum: Lorentz invariance and the role of Bel-Robinson tensor
Ana Alonso-Serrano, Marek Liška
Thermodynamics of local causal horizons have been shown to encode the information necessary to derive the equations governing the gravitational dynamics. We have previously shown t…
From spacetime thermodynamics to Weyl transverse gravity
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
There exist two consistent theories of self-interacting gravitons: general relativity and Weyl transverse gravity. The latter has the same classical solutions as general relativity…
Emergent Time and Time Travel in Quantum Physics
Ana Alonso-Serrano, Sebastian Schuster, Matt Visser
Entertaining the possibility of time travel will invariably challenge dearly held concepts of fundamental physics. It becomes relatively easy to construct multiple logical contradi…
Analytic Primordial Power Spectrum in the Dressed Metric Approach to Loop Quantum Cosmology and Thermodynamics of Spacetime
Ana Alonso-Serrano, Guillermo A. Mena Marugan, Antonio Vicente-Becerril
We investigate the primordial power spectrum of cosmological tensor perturbations in the dressed metric approach to Loop Quantum Cosmology. We compute the background-dependent effe…
Thermodynamics as a tool for (quantum) gravitational dynamics
Ana Alonso-Serrano, Marek Liška
The thermodynamics of local causal horizons has been shown to imply gravitational dynamics. In this essay, we discuss the principles underlying this observation, and its significan…
Friedmann equations and cosmic bounce in a modified cosmological scenario
Ana Alonso-Serrano, Marek Liška, Antonio Vicente-Becerril
In this work we present a derivation of modified Raychaudhuri and Friedmann equations from a phenomenological model of quantum gravity based on the thermodynamics of spacetime. Sta…
Emergence of quadratic gravity from entanglement equilibrium
Ana Alonso-Serrano, Marek Liška
In this work, we derive the linearised equations of quadratic gravity from entanglement equilibrium of local causal diamonds. Rather than starting from the Wald entropy prescriptio…
Noether charge formalism for Weyl invariant theories of gravity
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
Gravitational theories invariant under transverse diffeomorphisms and Weyl transformations have the same classical solutions as the corresponding fully diffeomorphism invariant the…
Noether charge formalism for Weyl transverse gravity
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
Weyl transverse gravity is a gravitational theory that is invariant under transverse diffeomorphisms and Weyl transformations. It is characterised by having the same classical solu…
Thermodynamics of spacetime and unimodular gravity
Ana Alonso-Serrano, Marek Liška
In this review we discuss emergence of unimodular gravity (or, more precisely, Weyl transverse gravity) from thermodynamics of spacetime. By analyzing three different ways to obtai…
Thermodynamics of spacetime from minimal area
Ana Alonso-Serrano, Marek Liška
Motivated by exploring the interface between thermodynamics of spacetime and quantum gravity effects, we develop a heuristic derivation of Hawking temperature and Bekenstein entrop…
Quantum phenomenological gravitational dynamics: A general view from thermodynamics of spacetime
Ana Alonso-Serrano, Marek Liška
In this work we derive general quantum phenomenological equations of gravitational dynamics and analyse its features. The derivation uses the formalism developed in thermodynamics…
Nonextensive Black Hole Entropy and Quantum Gravity Effects at the Last Stages of Evaporation
Ana Alonso-Serrano, Mariusz P. Dabrowski, Hussain Gohar
We analyze the Generalized Uncertainty Principle (GUP) impact onto the nonextensive black hole thermodynamics by using Rényi entropy. We show that when introducing GUP effects, bot…
New perspective on thermodynamics of spacetime: The emergence of unimodular gravity and the equivalence of entropies
Ana Alonso-Serrano, Marek Liška
We present a novel derivation of Einstein equations from the balance between Clausius entropy crossing the boundary of a local causal diamond and entanglement entropy associated wi…
Quantum approach to a Bianchi I singularity
Ana Alonso-Serrano, Martin Bojowald, David Brizuela
The approach of a quantum state to a cosmological singularity is studied through the evolution of its moments in a simple version of a Bianchi I model. In spite of the simplicity,…
Minimal length and the flow of entropy from black holes
Ana Alonso-Serrano, Mariusz P. Dabrowski, Hussain Gohar
The existence of a minimal length, predicted by different theories of quantum gravity, can be phenomenologically described in terms of a generalized uncertainty principle. We consi…
Generalized uncertainty principle impact onto the black holes information flux and the sparsity of Hawking radiation
Ana Alonso-Serrano, Mariusz P. Dabrowski, Hussain Gohar
We investigate the generalized uncertainty principle (GUP) corrections to the entropy content and the information flux of black holes, as well as the corrections to the sparsity of…
quantum cosmology: avoiding the Big Rip
Ana Alonso-Serrano, Mariam Bouhmadi-Lopez, Prado Martin-Moruno
Extended theories of gravity have gathered a lot of attention over the last years, for they not only provide an excellent framework to describe the inflationary era but also yields…
Correlations across horizons in quantum cosmology
Ana Alonso-Serrano, Luis J. Garay, Guillermo A. Mena Marugan
Different spacetime regions separated by horizons are not related to each other. We know that this statement holds for classical spacetimes. In this paper we carry out a canonical…
