Chaos and Taub-NUT related spacetimes
The occurrence of chaos for test particles moving in a Taub-NUT spacetime with a dipolar halo perturbation is studied using Poincaré sections. We find that the NUT parameter (magnetic mass) attenuates the presence of chaos. PACS numbers: 04.20.Jb, 04.70.Bw, 05.45.+b.

متن کاملThermodynamics of ( d + 1 ) - dimensional NUT - charged AdS Spacetimes
We consider the thermodynamic properties of (d+ 1)-dimensional spacetimes with NUT charges. Such spacetimes are asymptotically locally anti de Sitter (or flat), with non-trivial topology in their spatial sections, and can have fixed point sets of the Euclidean time symmetry that are either (d − 1)-dimensional (called ”bolts”) or of lower dimensionality (pure ”NUTs”). We compute the free energy,...
متن کاملClifford Algebroids and Nonholonomic Spinor Deformations of Taub–NUT Spacetimes
In this paper we examine a new class of five dimensional (5D) exact solutions in extra dimension gravity possessing Lie algebroid symmetry. The constructions provide a motivation for the theory of Clifford nonholonomic algebroids elaborated in Ref. [1]. Such Einstein–Dirac spacetimes are parametrized by generic off–diagonal metrics and nonholonomic frames (vielbeins) with associated nonlinear c...
متن کاملHidden Symmetry of Higher Dimensional Kerr–NUT–AdS Spacetimes
It is well known that 4–dimensional Kerr–NUT–AdS spacetime possesses the hidden symmetry associated with the Killing–Yano tensor. This tensor is ‘universal’ in the sense that there exist coordinates where it does not depend on any of the free parameters of the metric. Recently the general higher dimensional Kerr–NUT–AdS solutions of the Einstein equations were obtained. We demonstrate that all ...
متن کاملJu l 2 00 1 Non - existence of f - symbols in generalized Taub - NUT spacetimes
In a previous article it was proved that the extensions of the TaubNUT geometry do not admit Killing-Yano tensors, even if they possess Stäckel-Killing tensors. Here the analysis is taken further, and it is shown that, in general, this class of metrics does not even admit fsymbols. The only exception is the original Taub-NUT metric which possesses four Killing-Yano tensors of valence two. 1 Ext...
