Gedanken Experiments to Destroy a Black Hole by a Test Particle: Multiply Charged Black Hole with Higher Derivative Corrections
Keisuke Izumi, Toshifumi Noumi, Daisuke Yoshida
We investigate a gedanken experiment to destroy an extremally charged black hole by dropping a test particle, provided that there are multiple gauge fields coupled with each…
