Abstract
Static charged black holes in the presence of a negative cosmological constant and with a planar horizon are found in four dimensions The solutions have scalar secondary hair We claim that these constitute the planar version of the MartínezTroncosoZanelli black holes only known up to now for a curved event horizon in four dimensions Their planar version is rendered possible due to the presence of two equal and homogeneously distributed axionic charges dressing the flat horizon The solutions are presented in the conformal and minimal frame and their basic properties and thermodynamics analysed Entertaining recent applications to holographic superconductors we expose two branches of solutions the undressed axionic ReissnerNordströmAdS black hole and the novel black hole carrying secondary hair We show that there is a critical temperature at which the bald axionic ReissnerNordströmAdS black hole undergoes a second order phase transition to the hairy black hole spontaneously acquiring scalar hairThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
