标题： A higher dimensional generalization of the Kitaev spin liquid

摘要： 我们构建了一个可精确求解的四维Kitaev自旋液体模型。晶格结构为正交晶系，每个单胞包含六个亚点阵自由度。我们证明了该模型的费米面由二维曲面组成。此外，我们利用散射理论评估了产生涡旋粒子（visons）的能量代价。正的键翻转能量表明系统的基态无通量，类似于二维Kitaev蜂窝模型。我们的模型揭示了高维分数化实现的可能性。高维分数化。 显示英文摘要

摘要： We construct an exactly solvable model of a four-dimensional Kitaev spin liquid. The lattice structure is orthorhombic and each unit-cell contains six sublattice degrees of freedom. We demonstrate that the Fermi surface of the model is made up of two-dimensional surfaces. Additionally, we evaluate the energy cost of creating visons using scattering theory. The positive bond-flip energy suggests that the system's ground state is flux-free, similar to the two-dimensional Kitaev honeycomb model. Our model sheds light on the realization of high-dimensional fractionalization. high-dimensional fractionalization.
