Computing edge states without hard truncation
Kyle Thicke, Alexander B. Watson, Jianfeng Lu
We present a numerical method which accurately computes the discrete spectrum and associated bound states of Hamiltonians which model electronic "edge" states localized at boundari…

Dirac operators and domain walls
Jianfeng Lu, Alexander B. Watson, Michael I. Weinstein
We study the eigenvalue problem for a one-dimensional Dirac operator with a spatially varying ``mass'' term. It is well-known that when the mass function has the form of a kink, or…
