Finite Matter Resolution of the Cosmological Entropy Problem
L. Clavelli
We discuss how entropy bounds, which are not respected in the standard cosmology, constrain the parameters of a previously suggested cosmology with a finite total mass. In that alt…
On the Global Casimir Effect in the Schwarzschild Spacetime
C. R. Muniz, M. O. Tahim, M. S. Cunha +1
In this paper we study the vacuum quantum fluctuations of the stationary modes of an uncharged scalar field with mass around a Schwarzschild black hole with mass , at zero a…
Proof of the averaged null energy condition in a classical curved spacetime using a null-projected quantum inequality
Eleni-Alexandra Kontou, Ken D. Olum
Quantum inequalities are constraints on how negative the weighted average of the renormalized stress-energy tensor of a quantum field can be. A null-projected quantum inequality ca…
State of matter at high density and entropy bounds
Ali Masoumi
Entropy of all systems that we understand well is proportional to their volumes except for black holes given by their horizon area. This makes the microstates of any quantum theory…
