摘要:
经典自旋液体(CSLs)已被证明是涌现奇异规范理论的富有成效的场所。CSL中的空位团簇可以向系统中引入规范电荷,由此产生的行为反过来揭示了底层理论的性质。我们针对蜂窝晶格上的一系列CSL研究了这些效应。我们发现稀释导致了有效自由自旋的出现,其大小可调且通常为无理数。对于一个由对称张量规范场描述的特定高阶CSL,稀释产生了具有特征四极角结构的非衰减自旋纹理,以及稀释团簇之间的无限程相互作用。
英文摘要:
Classical spin liquids (CSLs) have proved to be a fruitful setting for the emergence of exotic gauge theories. Vacancy clusters in CSLs can introduce gauge charges into the system, and the resulting behavior in turn reveals the nature of the underlying theory. We study these effects for a series of CSLs on the honeycomb lattice. We find that dilution leads to the emergence of effective free spins with tuneable, and generally irrational, size. For a specific higher-rank CSL, described by a symmetric tensor gauge fields, dilution produces non-decaying spin textures with a characteristic quadrupolar angular structure, and infinite-ranged interactions between dilution clusters.
