Abstract Scope |
Recent progresses in nanoscale atomic manipulation and in the understanding of the topological properties of organic polymers offer new opportunities for the bottom-up synthesis of topologically-non-trivial artificial lattices, with possible use in quantum sensing and computing. With this regard, the dependence of topological properties on the shape or geometries of the nanostructures formed with these artificial lattices are largely unexplored. In this work, we employ a high throughput tight binding based framework to compute the topological invariant of the several different geometries of two-dimensional nanoribbons. A Monte Carlo based search technique is used to sample the huge design space. The topological classification is based on the quantized value of the intercell Zak phase for a given unit cell. The intercell Zak phase is obtained from the 1D Hybrid Wannier Charge centers computed by solving the tight-binding Hamiltonian. |
