Higher-dimensional generalization of the Kitaev spin liquid
Abstract
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 flux-free state is locally stable. Our model sheds light on the realization of high-dimensional fractionalization.
