石墨烯的显着性能使其纯的和人工的形式在当前的研究中最有吸引力的材料之一，主要关注的是在胡子和锯齿形边缘的拓扑边缘状态。在我们的工作中，我们利用这些准一维（1D）系统的量子输运和量子随机行走，并研究如何在这些边缘的两粒子量子态的演变。我们发现它们的量子关联动力学明显受到晶格几何的影响，并详细说明了与真正的一维晶格的差异。
Its remarkable properties render graphene-in its pure and artificial forms-one of the most attractive materials in current research, with major attention given to the topological edge states at the bearded and zigzag edge. In our work, we exploit these quasi-one-dimensional (1D) systems in terms of quantum transport and quantum random walks and investigate how two-particle quantum states evolve at these edges. We find that their quantum correlation dynamics are clearly influenced by the lattice geometry and elaborate on the differences to those in genuine 1D lattices.
