Super-Penrose process and rotating wormholes
arXiv:1807.11033 · doi:10.1103/PhysRevD.98.104030
Abstract
We consider collision of particles in a wormhole near its throat. Particles come from the opposite mouths. If the lapse function is small enough there, the energy of debris at infinity grows unbounded, so we are faced with the so-called super-Penrose process. This requires the existence of the ergoregion, so a wormhole should be rotating.
