Phonon-assisted insulator-metal transitions in correlated systems driven by doping
E. I. Shneyder, M. V. Zotova, S. V. Nikolaev +1
We consider how electron-phonon interaction influences the insulator-metal transitions driven by doping in the strongly correlated system. Using the polaronic version of the genera…

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…
