No logarithmic corrections to entropy in shift-symmetric Gauss-Bonnet gravity
Marek Liška, Robie A. Hennigar, David Kubizňák
Employing the covariant phase space formalism, we discuss black hole thermodynamics in four-dimensional scalar-tensor Einstein-Gauss-Bonnet gravity. We argue that logarithmic corre…
Can Bekenstein's area law prevail in modified theories of gravity?
David Kubizňák, Marek Liška
According to Bekenstein's area law, the black hole entropy is identified holographically -- with one quarter of the horizon area. However, it is commonly believed that such a law i…
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…
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…
