Boson Shells Harbouring Charged Black Holes

Abstract

We consider boson shells in scalar electrodynamics coupled to Einstein gravity. The interior of the shells can be empty space, or harbour a black hole or a naked singularity. We analyze the properties of these types of solutions and determine their domains of existence. We investigate the energy conditions and present mass formulae for the composite black hole--boson shell systems. We demonstrate that these types of solutions violate black hole uniqueness.
