Infinite chain of zero-range potentials having the Hamiltonian with infinite number of eigenvalues below the continuous spectrum is constructed. The model is based on the theory of self-adjoint extensions of symmetric operators.
Keywords: operator extensions theory, singular perturbation, point spectrum.
