Understand

We investigate the Cosmic Censorship Conjecture by means of the horizon wave-function (HWF) formalism.

We consider a charged massive particle whose quantum mechanical state is represented by a spherically symmetric Gaussian wave-function, and restrict our attention to the superxtremal case (with charge-to-mass ratio $\alpha>1$), which is the prototype of a naked singularity in the classical theory.
We find that one can still obtain a normalisable HWF for $\alpha^2<{2}$, and this configuration has a non-vanishing probability of being a black hole, thus extending the classically allowed region for a charged black hole.
However, the HWF is not normalisable for $\alpha^2 > 2$, and the uncertainty in the location of the horizon blows up at $\alpha^2=2$, signalling that such an object is no more well-defined.
