PESs of the MV-3 model. Curvatures are exaggerated. is reorganization energy. The fat horizontal bars are vibronic energy levels. aa + bb and aa − bb denote approximate wave functions for the given energy levels. For , , and the SDW-PES is lower than CDW-PES. Fat arrows show the behavior of CDW-PES at applied pressure. is defined by (2).
