A Classical Instability of Reissner-Nordstrom Solutions and the Fate of Magnetically Charged Black Holes

arXiv:hep-th/9111045 · doi:10.1103/PhysRevLett.68.1100

Abstract

Working in the context of spontaneously broken gauge theories, we show that the magnetically charged Reissner-Nordstrom solution develops a classical instability if the horizon is sufficiently small. This instability has significant implications for the evolution of a magnetically charged black hole. In particular, it leads to the possibility that such a hole could evaporate completely, leaving in its place a nonsingular magnetic monopole.
