G. W. Gibbons, T. Houri, D. Kubiznak, C. M. Warnick

摘要:

通过将类光的Escherart提升应用于几个已知的允许高阶动量运动积分的低维可积系统的例子,我们得到了具有不可约高阶Killing张量的四维和高维洛伦兹时空.我们相信,这样的度规是时空接纳高阶基林张量的第一个例子。在我们的例子中包括一个四维超对称pp波时空,其测地线流是超可积的。Killing张量满足非平凡Poisson-Schouten-Nijenhuis代数。我们讨论的扩展到量子制度。

英文摘要:

By applying the lightlike Eisenhart lift to several known examples of low-dimensional integrable systems admitting integrals of motion of higher-order in momenta, we obtain four- and higher-dimensional Lorentzian spacetimes with irreducible higher-rank Killing tensors. Such metrics, we believe, are first examples of spacetimes admitting higher-rank Killing tensors. Included in our examples is a four-dimensional supersymmetric pp-wave spacetime, whose geodesic flow is superintegrable. The Killing tensors satisfy a non-trivial Poisson-Schouten-Nijenhuis algebra. We discuss the extension to the quantum regime.
