G. Bianconi: Gravity from Entropy

[antaris]

Hi all,

I just want to know what you suggest to the arxiv papers of Prof. G. Bianconi.

Especially these two:
Gravity from Entropy
Quantum entropy couples matter with geometry

​

Thanks in advance.

Gravity from Entropy
Quantum entropy couples matter with geometry

So as I read correct the first paper describes an lorentzian spacetime and the second describes an discrete spacetime from higher order networks.

Both documents use an entropy–based variational principle in which the gravitational dynamics
(or network geometry dynamics in the discrete case) arise from a quantum relative entropy
between a default (or bare) metric and an induced metric determined by matter (and gauge)
fields. The continuum version formulates these ideas in the language of differential geometry and
field theory, while the discrete version adapts them to the combinatorial and algebraic setting
of higher–order networks. In both cases the formalism is consistent and the derived equations
(Einstein equations, Klein–Gordon and Dirac equations) are recovered in appropriate limits.

The discrete version leads to the Dirac- and Klein-Gordon-Equotation and the continuum version leads to macroscopic spacetime of the RT. Is this right?
