Description:
Author(s): Wen-Yu He, Xiao Yan Xu, Gang Chen, K. T. Law, and Patrick A. Lee 1 T − Ta S 2 is a cluster Mott insulator on the triangular lattice with 13 Ta atoms forming a star of David cluster as the unit cell. We derive a two-dimensional X X Z spin- 1 / 2 model with a four-spin ring exchange term to describe the effective low energy physics of a monolayer 1 T − Ta S 2 , where the effective... [Phys. Rev.
