Polaron transformations in the realistic model of the strongly correlated electron system
E. I. Shneyder, S. V. Nikolaev, M. V. Zotova +2
Electron-phonon coupling, diagonal in a real space formulation, leads to polaron paradigm of smoothly varying properties. However, fundamental changes, namely the singular behavior…

Effect of CuO2 lattice strain on the electronic structure and properties of high-Tc cuprate family
Ilya Makarov, Vladimir Gavrichkov, Elena Shneyder +4
Doping and strain dependences of the electronic structure of the CuO6-octahedra layer within LDA+GTB method in the frameworks of six-band p-d model are calculated. Band structure a…

Phonon and Magnetic Pairing Mechanisms in High-Temperature Superconductors in the Strong Correlation Mode
E. I. Shneyder, S. G. Ovchinnikov
The t-t'-t''-J model of electrons interacting with three phonon modes (breathing, apical breathing, and buckling) is considered. The wave-vector dependence of the matrix elements o…
