Negative energy states in the Reissner-Nordstr\"om metric
Abstract
We consider electrogeodesics on which the energy E<0 in the Reissner-Nordstr\"om metric. It is shown that outside the horizon there is exactly one turning point inside the ergoregion for such particles. This entails that such a particle passes through an infinite chain of black-white hole regions or terminates in the singularity. These properties are relevant for two scenarios of high energy collisions in which the presence of white holes is essential.
