Topological states in the Kronig–Penney model with arbitrary scattering potentials

We use an exact solution to the fundamental finite Kronig–Penney model with arbitrary positions and strengths of scattering sites to show that this iconic model can possess topologically nontrivial properties. By using free parameters of the system as extra dimensions we demonstrate the appearance o...
