Twisting versus bending in quantum waveguides
We make an overview of spectral-geometric effects of twisting and bending in quantum waveguides modelled by the Dirichlet Laplacian in an unbounded three-dimensional tube of uniform cross-section....

Absolute continuity of the spectrum in a twisted Dirichlet-Neumann waveguide
Quantum waveguides with the shape of a planar infinite straight strip and combined Dirichlet and Neumann boundary conditions on the opposite half-lines of the boundary are considered. The absence of the point as well as of the singu...

Distant Perturbation Asymptotics in Window-coupled Waveguides
We consider a pair of straight adjacent quantum waveguides of constant and in general of different widths coupled laterally by a pair of windows in the common boundary. We analyze the asymptotic behavior of the discrete spectrum....

Generation of paired photons in a quantum separable state in Bragg reflection waveguides
This work proposes and analyses a novel approach for the generation of separable (quantum uncorrelated) photon pairs based on spontaneous parametric down-conversion in Bragg reflection waveguides composed of semiconductor AlGaN laye...
