Decay of charged particles near naked singularities and super-Penrose process without fine-tuning

Abstract

We consider the Penrose process near the naked singularity in the Reissner-Nordström metric. Particle 0 falls from infinity and decays to two fragments at some point $r_0$. We show that the energy extraction due to this process can be indefinitely large in the limit $r_0\to 0$. In doing so, the value of the particle charge can remain bounded, in contrast to the previously known examples of the Penrose process in the electric field with unbounded energy extraction. The effect persists even in the limit of the flat pace-time.
