Analytic Topological Dyonic Hairy Black Hole and Thermodynamics

Abstract

•We solve coupled Einstein-Maxwell-Scalar gravity system to obtain a new family of dyonic-charged-hairy black hole solutions that possess both electric and magnetic charge with planar, spherical and hyperbolic horizon topologies in asymptotic AdS space. •We investigate the thermodynamics of this system and find drastic changes in its thermodynamical structure in the presence of a scalar field. •We favour these black holes for their stable nature at low temperatures in the case of the planar and hyperbolic horizon. •The thermodynamic phase diagram of the spherical hairy dyonic black hole at constant potential resembles to that of a Van der Waals fluid
