Abstract

Motivated by the recent appearance of the trillium lattice in the search for materials hosting spin liquids, we study the ground state of the classical Heisenberg model on its line graph, the trilline lattice. We find that this network realizes the recently proposed notion of a fragile spin liquid in three dimensions. Additionally, we analyze the Ising case and argue for a possible Z2 quantum spin liquid phase in the corresponding quantum dimer model. Like the well-known U(1) spin liquids, the classical phase hosts moment fractionalization evidenced by the diluted lattice, but unlike those, it exhibits exponential decay in both spin correlations and interactions between fractionalized moments. This provides an instance of a purely short-range correlated classical Heisenberg spin liquid in three dimensions.

三维脆性自旋液体

由于最近在寻找承载自旋液体的材料中出现了万亿晶格，我们研究了经典海森堡模型在其线形图上的基态，即万亿晶格。我们发现这个网络实现了最近提出的三维脆性自旋液体的概念。此外，我们分析了Ising情况，并在相应的量子二聚体模型中论证了可能存在的Z2量子自旋液相。与众所周知的U(1)自旋液体一样，经典相具有由稀释晶格证明的矩分数化，但与之不同的是，它在自旋相关和分数化矩之间的相互作用中都表现出指数衰减。这提供了三维空间中纯短程相关经典海森堡自旋液体的一个实例。2025年由美国物理学会出版
