Embedding spins in a line shape (line embedding) with cluster density matrix embedding theory (CDMET) is used to study distant spin correlations and entanglement entropy in the quantum spin liquid (QSL) of the spin‐1/2 J 1–J 2–J 3 Heisenberg model on the honeycomb lattice. It is found that, in the QSL, the reduced density matrix of two distantly separated spins is close to the direct product of the two reduced density matrices, which respectively belong to these two spins. This means that the spin correlations between these two distantly separated spins are vanishing. The QSL has short‐range Néel‐like order but loses long‐range orders. The spin expectation values in the QSL are very small. Distant spin correlations, which are sensitive to phase transitions, indicate that the QSL is isotropic. The QSL has a highly entangled ground state.

蜂窝晶格上量子自旋液体中的远距离自旋相关性
使用簇密度矩阵嵌入理论（CDMET）将自旋嵌入线形（线嵌入）用于研究自旋1/2 J 1 – J 2 –的量子自旋液体（QSL）中的远距离自旋相关性和纠缠熵。Ĵ 3蜂窝格上的海森堡模型。发现在QSL中，两个远距离分离的自旋的密度约简矩阵接近于分别属于这两个自旋的两个密度约简矩阵的直接乘积。这意味着这两个相距很远的自旋之间的自旋相关性正在消失。QSL具有类似Néel的短线定单，但丢失了长线定单。QSL中的旋转期望值非常小。对相变敏感的远距离自旋相关性表明QSL是各向同性的。QSL具有高度纠缠的基态。
