Four-Dimensional Asymptotically AdS Black Holes with Scalar Hair

Understand

We present a new family of asymptotically AdS four-dimensional black hole solutions with scalar hair of a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential.

• For a certain profile of the scalar field we solve the Einstein equations and we determine the scalar potential.
• Thermodynamically we show that there is a critical temperature below which there is a phase transition of a black hole with hyperbolic horizon to the new hairy black hole configuration.
