title: Continuum remover-complex absorbing potential: Efficient removal of the nonphysical stabilization points.
abstract: By adding a negative imaginary potential of variable strength eta to the Hamiltonian, the resonance state of a system can be found as complex energy stabilized points in the eta-trajectories of the eigenvalues. One problem that arises in practical calculations is the appearance of nonphysical complex energy stabilized points. A new method for separating the physical from the nonphysical complex energy stabilized points is proposed. The method is best illustrated with strongly correlated two-electron systems.
