Charged black holes in Einsteinian cubic gravity and nonuniqueness

Understand

Black holes are the simplest objects in the universe.

• They correspond to extreme deformations of spacetime geometry, and can exist even devoid of matter.
• In general relativity, (electro)vacuum black holes are uniquely determined by their mass, charge and angular momentum.
• This feature follows from a uniqueness theorem, which can be evaded if one considers higher dimensions or matter fields coupled to gravity.
