A trace formula for metric graphs with piecewise constant potentials and multi-mode graphs
(2022)
Journal Article
We generalize the scattering approach to quantum graphs to quantum graphs with piecewise constant potentials and multiple excitation modes. The free single-mode case is well-known and leads to the trace formulas of Roth (1983 C. R. Acad. Sci., Paris...
