These insights can allow incredibly accurate results to be obtained using only the lowest-order terms in a perturbation series. Yet perturbation theory represents only one method for approximating the exact energy, and few other methods have been considered through similar complex non-Hermitian extensions. diff --git a/Manuscript/fig1b.pdf b/Manuscript/fig1b.pdf index 80d55c4..c1d358a 100644 Binary files a/Manuscript/fig1b.pdf and b/Manuscript/fig1b.pdf differ
