Itinerant vibronic polarons: A Merrifield approach I. Low energy range calculations
S. G. Tsintsarska, M. D. Ivanovich, A. Andreev +3
We extend Merrifield's Variational Ansatz in the variational band theory of polarons to cover a frame of two electronic bands mixed by an Einstein phonon. The Hamiltonian is compos…
