Group Theoretical Quantization of Schwarzschild and Taub-NUT
Stationary spherically symmetric gravity is equivalent to a nonlinear coset sigma model on SL(2,IR)/SO(2) coupled to a gravitational remnant. Classically there are stationary solutions besides the static Schwarzschild metric labeled by the Schwarzschild mass m and the Taub-NUT charge l. Imposing the SL(2,IR) symmetry at the quantum level the Wheeler-DeWitt equation becomes related to the Casimi...
متن کاملSupersymmetry and the Geometry of Taub-NUT
The supersymmetric extension of Taub-NUT space admits 4 standard supersymmetries plus several additional non-standard ones. The geometrical origin of these symmetries is traced, and their algebraic structure is clarified. The result has applications to fermion modes in gravitational instantons as well as in long-range monopole dynamics. The low-energy dynamics of spinning particles in a curved ...
متن کاملBlack Rings in Taub-NUT
We construct the most generic three-charge, three-dipole-charge, BPS black-ring solutions in a Taub-NUT background. These solutions depend on seven charges and six moduli, and interpolate between a four-dimensional black hole and a five-dimensional black ring. They are also instrumental in determining the correct microscopic description of the five-dimensional BPS black rings.
متن کاملBranes, Instantons, And Taub-NUT Spaces
ALE and Taub-NUT (or ALF) hyper-Kahler four-manifolds can be naturally constructed as hyper-Kahler quotients. In the ALE case, this construction has long been understood in terms of D-branes; here we give a D-brane derivation in the Taub-NUT case. Likewise, instantons on ALE spaces and on Taub-NUT spaces have ADHM-like constructions related to hyper-Kahler quotients. Here we refine the analysis...
متن کاملGeometric construction of new Taub-NUT instantons
In this paper we exhibit a one-parameter family of new Taub-NUT instantons via connecting the two previously known SU(2) Yang–Mills instantons of unit charge on TaubNUT space by a half-line. The endpoint of the half-line will be the reducible Yang–Mills instanton corresponding to the Eguchi–Hanson–Gibbons L2 harmonic 2-form, while at an inner point we recover the Pope–Yuille instanton construct...
