圈量子引力黑洞的任意子统计和大视界态射

Anyonic statistics and large horizon diffeomorphisms for Loop Quantum Gravity Black Holes

Andreas G. A. Pithis, Hans-Christian Ruiz Euler

摘要:

通过量子孤立视界与辫群的关系,我们研究了量子孤立视界的大量子态射对LQG黑洞统计的作用。为了这个目的,陈-西蒙斯理论的对称性被概括,特别是关于上述类型的非同态。对于穿孔球面视界,这些是$S^2$的映射类群的元素,它几乎同构于这个特定流形上的相应辫子群。二维量子实体的相互交换是通过辫子群实现的,使统计成为任意子。由此我们证明了基于$SU(2)_k$ -Chern-Simons理论的量子孤立视界LQG模型具有非阿贝尔的任意子统计特性。通过这种方式,分数量子霍尔效应和拓扑量子计算背后的理论建立了联系,其中非阿贝尔任意子发挥了重要作用。

英文摘要:

We investigate the role played by large diffeomorphisms of quantum Isolated Horizons for the statistics of LQG Black Holes by means of their relation to the braid group. To this aim the symmetries of Chern-Simons theory are recapitulated with particular regard to the aforementioned type of diffeomorphisms. For the punctured spherical horizon, these are elements of the mapping class group of $S^2$, which is almost isomorphic to a corresponding braid group on this particular manifold. The mutual exchange of quantum entities in two dimensions is achieved by the braid group, rendering the statistics anyonic. With this we argue that the quantum Isolated Horizon model of LQG based on $SU(2)_k$-Chern-Simons theory explicitly exhibits non-abelian anyonic statistics. In this way a connection to the theory behind the fractional quantum Hall effect and that of topological quantum computation is established, where non-abelian anyons play a significant role.
