Vacuum Energy from Qubit Entropy
Gonçalo M. Quinta, Antonino Flachi
We develop a non-conventional description of the vacuum energy in quantum field theory in terms of quantum entropy. Precisely, we show that the vacuum energy of any non-interacting…
Entropy of extremal black holes: horizon limits through charged thin shells, a unified approach
José P. S. Lemos, Gonçalo M. Quinta, Oleg B. Zaslavskii
Using a unified approach we study the entropy of extremal black holes through the entropy of an electrically charged thin shell. We encounter three cases in which a shell can be ta…
Entropy of a self-gravitating electrically charged thin shell and the black hole limit
José P. S. Lemos, Gonçalo M. Quinta, Oleg B. Zaslavskii
A static self-gravitating electrically charged spherical thin shell embedded in a (3+1)-dimensional spacetime is used to study the thermodynamic and entropic properties of the corr…
