Abstract: In this note we elaborate on the convergence of the spectral gap of a class of discrete Schrödinger operators defined on a path graph in the limit of infinite volume. We confirm and extend recent results on the convergence of the spectral gap to a larger class of potentials using entirely different methods. Most importantly, we also resolve a conjecture previously proposed in this context. This then yields new insights into the rate at which the spectral gap tends to zero as the volume increases.
