摘要: It is pointed out that when a complex-Hamiltonian technique employed for solving Schrodinger's equation either in solids or atoms, the location of resonances cannot be accurately determined by specifying real energies at which imaginary part corresponding Green's function exhibits resonance peaks. Instead spanning energy axis to locate peaks electron DOS, it more accurate solve complex Hamiltonian entire plane. In particular, demonstrated locations an embedded atom are obtained direct diagonalization plane do not coincide general with DOS from approach.
