  By the use of the effective non-Hermitian Hamiltonian approach to scattering
we study the distribution of the scattering matrix (S-matrix) poles in
one-dimensional (1D) models with various types of diagonal disorder. We
consider the case of 1D tight-binding wires, with both on-site uncorrelated and
correlated disorder, coupled to the continuum through leads attached to the
wire edges. In particular, we focus on the location of the S-matrix poles in
the complex plane as a function of the coupling strength and the disorder
strength. Specific interest is paid to the super-radiance transition emerging
at the perfect coupling between wire and leads. We also study the effects of
correlations intentionally imposed to the wire disorder.
