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…
