论文摘要
我们在任意维度的一般卡洛利亚时空上研究了（共耦合）标量场。该分析揭示了电力和磁化动力学。对于这两个方面，我们都提供了田间的能量和动量，并伴随着它们的保护方程。我们讨论了由形成型异构体和相关电荷产生的保护和非保存特性。我们说明了标量场在四维ricci-flat Robinson-Trautman SpaceTimes上传播的标量场的结果。
We investigate the (conformally coupled) scalar field on a general Carrollian spacetime in arbitrary dimension. The analysis discloses electric and magnetic dynamics. For both, we provide the energy and the momenta of the field, accompanied by their conservation equations. We discuss the conservation and non-conservation properties resulting from the existence of conformal isometries and the associated charges. We illustrate those results for a scalar field propagating on the null boundary of four-dimensional Ricci-flat Robinson--Trautman spacetimes.
