Anyons和Double Copy

Anyons and the Double Copy

Daniel J Burger, William T. Emond, Nathan Moynihan

摘要:

我们研究了规范理论和引力中任意子的双拷贝结构。利用在壳层振幅技术,我们构造了描述具有自旋的大质量粒子的小群协变旋螺变量,它与局域性和么正性一起使我们能够导出任意子的长程树能级散射振幅.我们发现经典规范理论的任意子解以非平凡的方式复制到它们的引力对应物。有趣的是,我们表明,无质量的双副本捕获的拓扑结构的弯曲时空在三维空间中引入一个非平凡的混合拓扑引力子和puppon。最后,我们证明了著名的Aharonov-Bohm相位可以直接从构造的壳层振幅中导出,并且它也可以简单地复制到引力对应物中。

英文摘要:

We examine the double copy structure of anyons in gauge theory and gravity. Using on-shell amplitude techniques, we construct little group covariant spinor-helicity variables describing massive particles with spin, which together with locality and unitarity enables us to derive the long-range tree-level scattering amplitudes involving anyons. We discover that classical gauge theory anyon solutions double copy to their gravitational counterparts in a non-trivial manner. Interestingly, we show that the massless double copy captures the topological structure of curved spacetime in three dimensions by introducing a non-trivial mixing of the topological graviton and the dilaton. Finally, we show that the celebrated Aharonov-Bohm phase can be derived directly from the constructed on-shell amplitude and that it too enjoys a simple double copy to its gravitational counterpart.
