Reentrant phase transitions in EinsteinMaxwellScalar black holes
Abstract
We consider how scalar fields affect the thermodynamic behaviour of charged antide Sitter (AdS) black holes. We specifically investigate a class of (3+1)dimensional exact hairy charged AdS black hole solutions to EinsteinMaxwellscalar gravity, whose stable ground state and finite horizon area in the zero temperature limit make it of particular interest. We find that the reverse isoperimetric inequality is satisfied for this class, and that there exists an intermediate range of the charge that admits reentrant phase behaviour, the first example of this type of phase behaviour in (3+1)dimensions in a consistent theory.
