Evaporation and Antievaporation instabilities

Understand

We review (anti)evaporation phenomena within the context of quantum gravity and extended theories of gravity.

• The (anti)evaporation effect is an instability of the black hole horizon discovered in many different scenarios: quantum dilaton-gravity, $f(R)$-gravity, $f(T)$-gravity, string inspired black holes and brane-world cosmology.
• Evaporating and antievaporating black holes seem to have completely different thermodynamical features compared to standard semiclassical black holes.
• The purpose of this review is to provide an introduction to conceptual and technical aspects of (anti)evaporation effects, while discussing problems that are still open.
