Schwinger Effect in Near-extremal Charged Black Holes in High Dimensions
Rong-Gen Cai, Chiang-Mei Chen, Sang Pyo Kim +1
We study the Schwinger effect in near-extremal nonrotating black holes in an arbitrary -dimensional asymptotically flat and (A)dS space. Using the near-horizon geometry…

Charge Emission from Near-Extremal Charged Black Holes
Chiang-Mei Chen, Sang Pyo Kim, Jia-Rui Sun
Using the symmetry of the near-horizon geometry and applying quantum field theory of a complex scalar field, we study the spontaneous pair production of charged scalars from near-e…
