Quantum probes of repulsive singularities in ? 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 wavefunction 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.
