Probability current tornado loops in three-dimensional scattering
Pavel Exner, Petr Seba
We consider scattering of a three-dimensional particle on a finite family of delta potentials. For some parameter values the scattering wavenctions exhibit nodal lines in the form…
Evanescent modes in a multiple scattering factorization
Pavel Exner, Milos Tater
We discuss differences between the exact S-matrix for scattering on serial structures and a known factorized expression constructed of single-element S-matrices. As an illustration…
Bound-state asymptotic estimates for window-coupled Dirichlet strips and layers
Pavel Exner, Simeon Vugalter
We consider the discrete spectrum of the Dirichlet Laplacian on a manifold consisting of two adjacent parallel strips or planar layers coupled by a finite number N of windows in th…
A Mechanism of Porous-Silicon Luminescence
F. Bentosela, P. Exner, V. A. Zagrebnov
We discuss the discrete spectrum induced by bulges on threadlike mesoscopic objects, using two models, a continuous hard-wall waveguide and a discrete tight-binding model with two…
Topologically induced vortex magnetance of a quantum device
P. Exner, P. Seba, A. F. Sadreev +2
We consider resonant vortices around nodal points of the wavefunction in electron transport through a mesoscopic device. With a suitable choice of the device geometry, the dominati…
Resonance statistics in a microwave cavity with a thin antenna
P. Exner, P. Šeba
We propose a model for scattering in a flat resonator with a thin antenna. The results are applied to rectangular microwave cavities. We compute the resonance spacing distribution…
