弯曲时空中的相对定域性

Relative Locality in Curved Space-time

Jerzy Kowalski-Glikman, Giacomo Rosati

摘要:

在本文中,我们构造的作用量描述动力学的粒子运动在弯曲的时空,与一个非平凡的动量空间几何。弯曲的动量空间是相对局域性理论的核心特征。到目前为止,动量空间中的非线性方面的研究仅限于平坦或不断膨胀(De Sitter)时空,依赖于它们的最大对称性质。将弯曲的动量空间框架扩展到任意时空几何可能与测试粒子动量空间的普朗克尺度曲率/变形的机会有关。作为这种构造的第一个例子,我们描述了在史瓦西时空中的圆形轨道上具有卡帕-庞加莱动量空间的粒子,其中动量空间曲率的贡献是可以忽略的。这个问题的分析关键依赖于足球问题的解决方案。

英文摘要:

In this paper we construct the action describing dynamics of the particle moving in curved spacetime, with a non-trivial momentum space geometry. Curved momentum space is the core feature of theories where relative locality effects are presents. So far aspects of nonlinearities in momentum space have been studied only for flat or constantly expanding (De Sitter) spacetimes, relying on the their maximally symmetric nature. The extension of curved momentum space frameworks to arbitrary spacetime geometries could be relevant for the opportunities to test Planck-scale curvature/deformation of particles momentum space. As a first example of this construction we describe the particle with kappa-Poincaré momentum space on a circular orbit in Schwarzschild spacetime, where the contributes of momentum space curvature turn out to be negligible. The analysis of this problem relies crucially on the solution of the soccer ball problem.
