Abstract:

The Hermitian effective interaction can be well-approximated by (R + R^†)/2 if the eigenvalues of ω^†ω are small or state-independent (degenerate), where R is the standard non-Hermitian effective interaction and ω maps the model-space states onto the excluded space. An error bound on this approximation is given.
