On the spectrum of two quantum layers coupled by a window
Denis Borisov
We consider the Dirichlet Laplacian in a domain two three-dimensional parallel layers having common boundary and coupled by a window. The window produces the bound states below the…

Exponential splitting of bound states in a waveguide with a pair of distant windows
D. Borisov, P. Exner
We consider Laplacian in a straight planar strip with Dirichlet boundary which has two Neumann ``windows'' of the same length the centers of which are apart, and study the asy…
