For a quantum mechanically Gaussian shaped, electrically charged, massive particle, we compute the Horizon Wave-function(s) in order to study (a) the existence of the inner Cauchy horizon of the corresponding Reissner–Nordström space-time when the charge-to-mass ratio 0 < α < 1 and (b) the survival of a naked singularity when the charge-to-mass ratio α > 1. Our results suggest that any semi- classical instability one expects near the inner horizon may not occur in quantum black holes, with a mass around the Planck scale, and that no states with charge-to- mass ratio greater than a critical value (of the order of 2) should exist.

Abstract
For a quantum mechanically Gaussian shaped, electrically charged, massive particle, we compute the Horizon Wave-function(s) in order to study (a) the existence of the inner Cauchy horizon of the corresponding Reissner–Nordström space-time when the charge-to-mass ratio 0 < α < 1 and (b) the survival of a naked singularity when the charge-to-mass ratio α > 1. Our results suggest that any semi- classical instability one expects near the inner horizon may not occur in quantum black holes, with a mass around the Planck scale, and that no states with charge-to- mass ratio greater than a critical value (of the order of 2) should exist.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
