Spontaneous scalarization in Einstein–power–Maxwell–scalar models

Abstract

We study the spontaneous scalarization of charged black holes in Einstein’s gravity minimally coupled to power–Maxwell electrodynamics which, in turn, is non–minimally coupled to a real scalar field. We point out the existence of a specific power for which the scalarized solution is well-behaved, and entropically preferred in comparison to the scalar-free charged black hole solution.
