Energy extraction from a rotating black hole via magnetic reconnection: Bumblebee gravity
In a Kerr-Sen-like spacetime from Bumblebee gravity, increasing the Lorentz symmetry breaking rate and Bumblebee charge enlarges the allowed region for energy extraction via magnetic reconnection and moves it closer to the horizon, with peak efficiency when cosmic censorship is marginally violated.
