论文摘要
``卡罗尔颗粒移动吗?''答案取决于粒子的特征,例如其质量,自旋,电荷和磁矩。巨大的卡罗尔粒子(与分形密切相关)不会移动。它的不动性来自Carroll Boost对称性,这意味着偶极子保护,但不相反。无质量的卡罗尔粒子可以通过遵循霍尔定律来传播,与卡洛尔增强对称性的部分破裂保持一致。该框架扩展到卡洛尔场理论。在$ d = 2 $空间尺寸中,卡罗尔组具有两倍的中央扩展,使我们能够将动力学推广到包括Anyons在内的庞大而无质量的颗粒。 Anyonic自旋和磁矩与两个Casimir不变的参数化的双重延伸结构,这些结构被解释为内在的磁化和非交换性参数。受电磁背景场受到的延长卡罗尔粒子按照包括zeeman力量的广义霍尔定律移动。该理论用无质量的,未充电的人说明了我们称之为外来的光子的双重中心扩展的结构,后者在黑洞的地平线上移动,从而产生了任何人旋转的效果。
``Do Carroll particles move?'' The answer depends on the characteristics of the particle such as its mass, spin, electric charge, and magnetic moment. A massive Carroll particle (closely related to fractons) does not move; its immobility follows from Carroll boost symmetry which implies dipole conservation, but not conversely. A massless Carroll particle may propagate by following the Hall law, consistently with the partial breaking of the Carroll boost symmetry. The framework is extended to Carroll field theory. In $d=2$ space dimensions, the Carroll group has a two-fold central extension which allows us to generalize the dynamics to massive and massless particles, including anyons. The anyonic spin and magnetic moment combine with the doubly-extended structure parameterized by two Casimir invariants interpreted as intrinsic magnetization and non-commutativity parameter. The extended Carroll particle subjected to an electromagnetic background field moves following a generalized Hall law which includes a Zeeman force. This theory is illustrated by massless, uncharged anyons with doubly-centrally extended structure we call exotic photons, which move on the horizon of a Black Hole, giving rise to an anyonic spin-Hall Effect.
