Article Description

By adding a negative imaginary potential of variable strength η to the Hamiltonian, the resonance state of a system can be found as complex energy stabilized points in the η-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. © 2009 American Institute of Physics.
