Quantum Probes of Repulsive Singularities in N = 2 Supergravity

Abstract

Repulsive singularities (repulsons) in extended supergravity theories are investigated. These repulsive singularities are related to attractive singularities (black holes) in moduli space of extended supergravity vacua. In order to study these repulsive singularities a scalar test-particle in the background of a repulson is investigated. It is shown, using a partial wave expansion, that the wave function of the scalar particle vanishes at the curvature singularity at the origin. In addition the connection to higher dimensional p-brane solutions including anti-branes is discussed.
