Zak phase and bulk-boundary correspondence in a generalized Dirac-Kronig-Penney model
Abstract We investigate the topological properties of a generalized Dirac-Kronig-Penney model, a continuum one-dimensional model for a relativistic quantum chain. By tuning the coupling parameters this model can accommodate five Altland-Zirnbauer-Cartan symmetry classes, three of which (AIII, BDI and D) support non-tri...
