平坦时空中的全息术:边界上的4D理论和电磁对偶性

Holography in flat spacetime: 4D theories and electromagnetic duality on the border

Andrea Amoretti, Alessandro Braggio, Giacomo Caruso, Nicola Maggiore, Nicodemo Magnoli

摘要:

我们考虑一个自由的拓扑模型,在5D欧氏平坦时空,建立从两个秩2张量场。尽管该模型的大部分没有任何特定的物理解释,但在其4D平面边缘上恢复了非平凡的规范场理论,其特征完全由该模型的规范和离散对称性决定。特别是没有4D动力学可以获得不强加的时间Reynolds不变性的散装。值得注意的是,时间反射对称性选择的两种可能的边缘模型之一显示了真正的电磁对偶性,它涉及强耦合和弱耦合制度。此外,当考虑在壳层上时,这个相同的模型与麦克斯韦理论相一致,因此可以将其视为看似无害的5D拓扑模型的4D边界理论。

英文摘要:

We consider a free topological model in 5D euclidean flat spacetime, built from two rank-2 tensor fields. Despite the fact that the bulk of the model does not have any particular physical interpretation, on its 4D planar edge nontrivial gauge field theories are recovered, whose features are entirely determined by the gauge and discrete symmetries of the bulk. In particular no 4D dynamics can be obtained without imposing a Time Reversal invariance in the bulk. Remarkably, one of the two possible edge models selected by the Time Reversal symmetries displays a true electromagnetic duality, which relates strong and weak coupling regimes. Moreover this same model, when considered on-shell, coincides with the Maxwell theory, which therefore can be thought of as a 4D boundary theory of a seemingly harmless 5D topological model.
