Fano Resonances in Stubbed Quantum Waveguides with Impurities
G. Cattapan, P. Lotti
We consider T--shaped, two--dimensional quantum waveguides containing attractive or repulsive impurities with a smooth, realistic shape, and study how the resonance behavior of the…

S-Matrix Poles Close to Thresholds in Confined Geometries
G. Cattapan, P. Lotti
We have studied the behavior of the S-matrix poles near threshold for quantum waveguides coupled to a cavity with a defect. We emphasize the occurrence of both dominant and shadow…
