    "abstract": "The Schroedinger equation with an energy-dependent complex absorbing\npotential, associated with a scattering system, can be reduced for a special\nchoice of the energy-dependence to a harmonic inversion problem of a discrete\npseudo-time correlation function. An efficient formula for Green\u0027s function\nmatrix elements is also derived. Since the exact propagation up to time 2t can\nbe done with only t real matrix-vector products, this gives an unprecedently\nefficient scheme for accurate calculations of quantum spectra for possibly very\nlarge systems.",
