We discuss discuss spectral and scattering properties of a particle confined to a straight Dirichlet tube in $\mathbb{R}^3$ with a family of point interactions.
The Aharonov-Bohm Hamiltonian: self-adjointness, spectral and scattering properties
Approximation of Schrödinger operators with point interactions on bounded domains
Two interacting particles on the half-line: resolvent and scattering properties
