Hello, do local operator algebras only matter when you’re constructing a QFT or making approximations? In Witten’s paper (arXiv:1803.04993), he argues quite the opposite: the full Hilbert space H cannot be factorized into H_V ⊗ H_V′, since that would imply the vacuum splits into unentangled...

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)...

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.

Thank you very much. May I come back with new questions.

I meant whether the effect is realized in Hawking's theory, not whether it is actually realized in nature.

Ok, back to Hawking. Within the text below 1.2: Is Hawking's interpretation valid in general in curved space time with dynamic solutions (time depent, rotating bodies, gravitational collapse, evaporation)? The described effect is realized everywhere in curved space time but would be a lot to...

Is this only valid for Hawking's formulation of QFT in curved spacetime or in general? Regardless of Hawking's paper, can the starting point of a QFT also be any local Minkowski spacetime, such as the reference system of the Earth (in very good approximation -> asymptotic)?

link: "Particle Creation by Black Holes", S. Hawking [FONT=arial]Hello all, I just want to know the meaning of the text followed by equotation 1.2. Especially if the flat or asymptotic flat region could interpreted for Minkowski-Spacetime at an arbitary Point in M or just at the...
