Absolute continuity of the spectrum in a twisted Dirichlet-Neumann waveguide
arXiv:1906.05617 · doi:10.1063/1.5114994
Abstract
Quantum waveguide with the shape of planar infinite straight strip and combined Dirichlet and Neumann boundary conditions on the opposite half-lines of the boundary is considered. The absence of the point as well as of the singular continuous spectrum is proved.
