Abstract: We report the appearance of multiple numbers of completely flat band states in an extended Lieb lattice model in two dimensions with five atomic sites per unit cell. We also show that this edge-centered square… read more here.

DOI: 10.1103/physrevb.101.205143
Abstract: Recent experiments have shown the signatures of Majorana bound states at the ends of magnetic chains deposited on a superconducting substrate. Here, we employ first-principles calculations to directly investigate the topological properties of $3d$ transition… read more here.

DOI: 10.1103/physrevb.102.035145
Abstract: A two-dimensional (2D) topological band is characterized by the (first) Chern number. The zero and nonzero Chern numbers usually represent the trivial and nontrivial band topologies, respectively. In this paper, we study an extended Qi-Wu-Zhang… read more here.
