Angular Momentum Fluctuations
Marcelo Schiffer
In this paper, we consider angular momentum fluctuations of a Schwartzschild black hole in thermal equilibrium with radiation which, for the sake of simplicity is here modeled by a…

Charge Fluctuations of an Uncharged Black Hole
Marcelo Schiffer
In this paper we calculate charge fluctuations of a Schwarzschild black-hole of mass confined within a perfectly reflecting cavity of radius R in thermal equilibrium with vario…

Does the Cosmological Expansion Change Local Dynamics?
M. Schiffer
It is well a known fact that the Newtonian description of dynamics within Galaxies for its known matter content is in disagreement with the observations as the acceleration approac…
