Resonances in twisted quantum waveguides
H. Kovarik, A. Sacchetti
In this paper we consider embedded eigenvalues of a Schroedinger Hamiltonian in a waveguide induced by a symmetric perturbation. It is shown that these eigenvalues become unstable…

Estimates on trapped modes in deformed quantum layers
Hynek Kovarik, Semjon Vugalter
We use a logarithmic Lieb-Thirring inequality for two-dimensional Schroedinger operators and establish estimates on trapped modes in geometrically deformed quantum layers.
