Can quantum mechanics fool the cosmic censor?
G. E. A. Matsas, M. Richartz, A. Saa +2
We revisit the mechanism for violating the weak cosmic-censorship conjecture (WCCC) by overspinning a nearly-extreme charged black hole. The mechanism consists of an incoming massl…
Scalar radiation emitted from a rotating source around a Reissner-Nordstrom black hole
Luis C. B. Crispino, Andre R. R. da Silva, George E. A. Matsas
We investigate the radiation emitted from a scalar source in circular orbit around a Reissner-Nordstrom black hole. Particle and energy emission rates are analytically calculated i…
The Unruh effect and its applications
Luis C. B. Crispino, Atsushi Higuchi, George E. A. Matsas
It has been thirty years since the discovery of the Unruh effect. It has played a crucial role in our understanding that the particle content of a field theory is observer dependen…
Semiclassical approach to the decay of protons in circular motion under the influence of gravitational fields
Douglas Fregolente, George E. A. Matsas, Daniel A. T. Vanzella
We investigate the possible decay of protons in geodesic circular motion around neutral compact objects. Weak and strong decay rates and the associated emitted powers are calculate…
