费米子加倍定理的规范理论推广

A gauge theory generalization of the fermion-doubling theorem

S. M. Kravec, John McGreevy

摘要:

可以通过边缘态的性质来表征物质的某些状态。这意味着一个“仅表面模型”的概念:只能在高维系统的边缘正则化的模型。在将Nielsen和Ninomiya的费米子加倍结果纳入这个框架之后,我们采用这个想法来确定量子场论的保序调节器的新障碍。我们专注于一个例子,禁止规范模型的麦克斯韦理论与明显的电磁对偶对称性。

英文摘要:

It is possible to characterize certain states of matter by properties of their edge states. This implies a notion of `surface-only models': models which can only be regularized at the edge of a higher-dimensional system. After incorporating the fermion-doubling results of Nielsen and Ninomiya into this framework, we employ this idea to identify new obstructions to symmetry-preserving regulators of quantum field theory. We focus on an example which forbids regulated models of Maxwell theory with manifest electromagnetic duality symmetry.
