Schwinger Mechanism and Hawking Radiation as Quantum Tunneling

Understand

The common interpretation of the Hawking radiation as quantum tunneling has some ambiguity such as coordinate-dependence of tunneling rate and non-invariance of the action under canonical transformations.

• It is shown that the tunneling process of black holes can be successfully described by Rindler coordinates in analogy with the Schwinger mechanism for pair production.
• We study the tunneling process of a charged black hole and a BTZ black hole.
