Thermodynamics of a charged hairy black hole in (2+1) dimensions

Understand

In this paper we study thermodynamics, statistics and spectroscopic aspects of a charged black hole with a scalar hair coupled to the gravity in (2+1) dimensions.

• We obtained effects of the black hole charge and scalar field on the thermodynamical and statistical quantities.
• We find that scalar charge may increase entropy, temperature and probability, while may decrease black hole mass, free and internal energy.
• Also electric charge increases probability and decreases temperature and internal energy.
