In a collisional Penrose process, two particles coming from the asymptotically flat region collide in the ergosphere of a compact object. The collision produces two new particles, one with positive energy and one with negative energy. When the particle with positive energy escapes to infinity, the process extracts energy from the compact object. In this paper, we study the collisional Penrose process in a rotating wormhole spacetime. We consider the simple case of a head-on collision at the throat of a Teo wormhole. We find that the process of energy extraction from a Teo wormhole can be substantially more efficient than the collisional Penrose process in the Kerr black hole spacetime.

Dymnikova-Schwinger quantum-corrected slowly rotating wormholes: Photon and spinning particle dynamics
GUP-corrected rotating wormholes based on the Dymnikova-Schwinger profile produce split co- and counter-rotating photon spheres and asymmetric shadows.
