论文摘要
我们通过向单粒子汉密尔顿的现场排斥并解决簇扰动理论中的多体问题来研究3D晶体拓扑绝缘子中E-E相互作用的影响。目的是阐明多少身体效应改变了源于晶体对称性的拓扑阶段。调谐现场相互作用的强度，我们表明频带反转消失在散装状态和表面状态下的金属特性。
We study the effects of e-e interaction in a 3D Crystalline Topological Insulator by adding on-site repulsion to the single-particle Hamiltonian and solving the many-body problem within Cluster Perturbation Theory. The goal is to clarify how many body effects modify the topological phase that stems from the crystal symmetries. Tuning the strength of the on-site interaction we show that band inversion disappears in the bulk and surface states loose their metallic character.
