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…

The O-M-O triatomic molecule: Basic unit of cuprates & manganates
S. Tsintsarska, M. D. Ivanovich, M. Georgiev +1
The O(oxygen)-M(metal)-O(oxygen) molecule is a basic unit of high-temperature superconducting cuprates and colossal magnetoresistance exhibiting manganates. This molecule can be re…
