Bound States in the Continuum in Two-Dimensional Serial Structures
G. Cattapan, P. Lotti
We investigate the occurrence of bound states in the continuum (BIC's) in serial structures of quantum dots coupled to an external waveguide, when some characteristic length of the…

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…
