Supersymmetry and Stationary Solutions in Dilaton-Axion Gravity

arXiv:hep-th/9406059 · doi:10.1103/PhysRevD.50.6374

Abstract

New stationary solutions of -dimensional dilaton-axion gravity are presented, which correspond to the charged Taub-NUT and Israel-Wilson-Perjes (IWP) solutions of Einstein-Maxwell theory. The charged axion-dilaton Taub-NUT solutions are shown to have a number of interesting properties: i) manifest symmetry, ii) an infinite throat in an extremal limit, iii) the throat limit coincides with an exact CFT construction. The IWP solutions are shown to admit supersymmetric Killing spinors, when embedded in supergravity. This poses a problem for the interpretation of supersymmetric rotating solutions as physical ground states. In the context of -dimensional geometry, we show that dimensionally lifted versions of the IWP solutions are dual to certain gravitational waves in string theory.
