چکیده

The geodesic motion of pseudo-classical spinning particles in Euclidean Taub-NUT space is analysed. The constants of motion are expressed in terms of Killing-Yano tensors. Some previous results from the literature are corrected. PACS number(s): 04.20.Jb, 02.40.-K The con guration space of spinning particles (spinning space) is an supersymmetric extension of an ordinary Riemannian manifold, parametrized by local coordinates fx g, to a graded manifold parametrized by local coordinates fx ; g, with the rst set of variables being Grassmann even (commuting) and the second set, Grassmann odd (anticommuting). The equation of motion of a spinning particle on a geodesic is derived from the action:

Runge - Lenz Vector in Taub -nut Spinning Space

The generalized Killing equations and the symmetries of Taub-NUT spinning space are investigated. For spinless particles the Runge-Lenz vector defines a constant of motion directly, whereas for spinning particles it now requires a non-trivial contribution from spin. The generalized Runge-Lenz vector for spinning Taub-NUT space is completely evaluated. PACS. 04.20.Me Conservation laws and equati...

The Geodesic Motion in Taub-nut Spinning Space

The geodesic motion of pseudo-classical spinning particles in the Euclidean Taub-NUT space is analysed. The generalized Killing equations for spinning space are investigated and the constants of motion are derived in terms of the solutions of these equations. A simple exact solution, corresponding to trajectories lying on a cone, is given. E-mail address: [email protected]

Anholonomic Frames, Generalized Killing Equations, and Anisotropic Taub NUT Spinning Spaces

By using anholonomic frames in (pseudo) Riemannian spaces we define anisotropic extensions of Euclidean Taub–NUT spaces. With respect to coordinate frames such spaces are described by off-diagonal metrics which could be diagonalized by corresponding anholonomic transforms. We define the conditions when the 5D vacuum Einstein equations have as solutions anisotropic Taub–NUT spaces. The generaliz...

Supersymmetries and Constants of Motion in Taub-nut Spinning Space

We review the geodesic motion of pseudo-classical spinning particles in curved spaces. Investigating the generalized Killing equations for spinning spaces, we express the constants of motion in terms of KillingYano tensors. The general results are applied to the case of the fourdimensional Euclidean Taub-NUT spinning space. A simple exact solution, corresponding to trajectories lying on a cone,...

Supersymmetry 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 ...
