    Exponential splitting of bound states in a waveguide with a pair of distant windows

    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 2l2l apart, and study the asymptotic behaviour of the discrete spectrum as l→∞l\to\infty. It is shown that there are pairs of eigenvalues around each isolated eigenvalue of a single-window strip and their distances vanish exponentially in the limit l→∞l\to\infty. We derive an asymptotic expansion also in the case where a single window gives rise to a threshold resonance which the presence of the other window turns into a single isolated eigenvalue
