On relations between stable and Zeno dynamics in a leaky graph decay model
Pavel Exner, Takashi Ichinose, Sylwia Kondej
We use a caricature model of a system consisting of a quantum wire and a finite number of quantum dots, to discuss relation between the Zeno dynamics and the stable one which gover…
Leaky quantum wire and dots: a resonance model
Pavel Exner, Sylwia Kondej
We discuss a model of a leaky quantum wire and a family of quantum dots described by Laplacian in with an attractive singular perturbation supported by a line a…
Bound states due to a strong interaction supported by a curved surface
Pavel Exner, Sylwia Kondej
We study the Schrödinger operator in with a interaction supported by an infinite non-planar surface which is smooth, admits a global normal paramet…
On Eigenvalues Problem for Self-adjoint Operators with Singular Perturbations
Sylwia Kondej
We investigate the eigengenvalues problem for self-adjoint operators with the singular perturbations. The general results presented here includes weakly as well as strongly singula…
