Extreme black hole with an electric dipole moment.

We construct a new extreme black hole solution in a toroidally compactified heterotic string theory. The black hole saturates the Bogomol{close_quote}nyi bound, has zero angular momentum, but a nonzero electric dipole moment. It is obtained by starting with a higher-dimensional rotating charged black hole, and compactifying one direction in the plane of rotation. {copyright} {ital 1996 The American Physical Society.}
