标题： Dimerization in the SU(4) Heisenberg model on the cubic lattice: iPEPS study

摘要： 我们研究在立方晶格上具有空间各向异性磁耦合的SU(4)对称的海森堡模型。 我们利用基于多体波函数张量网络表示的几种方法，这些方法能够准确分析模型在不同空间各向异性区域的基态性质，包括完全各向同性的三维情况。 我们的结果表明，二聚化的颜色有序相在整个磁耦合范围内持续存在，仅排除完全解耦的一维链极限情况。 显示英文摘要

摘要： We study SU(4)-symmetric Heisenberg model on the cubic lattice with spatially anisotropic magnetic couplings. We utilize several approaches based on the tensor-network representation of the many-body wave functions, which enable accurate analysis of ground-state properties of the model in different regimes of spatial anisotropy including fully isotropic three-dimensional case. Our results point to the persistence of the dimerized color-ordered phase throughout whole range of magnetic couplings excluding only the limit of completely decoupled one-dimensional chains.
