偶极BF理论与偶极编织统计

Dipolar BF theory and dipolar braiding statistics

Jung Hoon Han

AI总结:

本文分析偶极BF理论,证明其与秩-2张量BF理论等价,并阐明偶极对称性在守恒律和编织统计中的体现。

摘要:

我们分析了最近提出的偶极BF理论及其与电荷和偶极电流的耦合。该理论中的准粒子分为电荷型或偶极型,电荷型与偶极型准粒子之间的相互编织统计是偶极性的,即它依赖于被环绕准粒子的位置。两个偶极型准粒子之间的编织统计与普通任意子相同。我们进一步证明了偶极BF理论等价于早期作为秩-2环面码有效理论而发展的秩-2张量BF理论。尽管这两个理论等价,但偶极BF表述明确体现了偶极对称性,并清晰地揭示了偶极对称性如何在各种守恒定律和偶极编织统计中体现。

英文摘要:

We analyze the recently proposed dipolar BF theory with couplings to charge and dipole currents. The quasiparticles of the theory are either charge-like or dipole-like, and the mutual braiding statistics between charge-like and dipole-like quasiparticles are dipolar, meaning that it depends on the position of the quasiparticle being encircled. The braiding statistics between two dipole-like quasiparticles is that of ordinary anyons. We further prove that the dipolar BF theory is equivalent to the rank-2 tensor BF theory developed earlier as an effective theory for the rank-2 toric code. Although the two theories are equivalent, the dipolar BF formulation embodies the dipole symmetry explicitly and gives a clean insight into the way the dipole symmetry manifests itself in various conservation laws and the dipolar braiding statistics.
