Local anharmonic effects in high-Tc superconductors. Pseudospin-electron model
Some aspects of physical phenomena in high-Tc crystals caused by anharmonicity of the crystal lattice are discussed. Appropriate theoretical models are considered. A review is given of the results obtained while investigating the pseudospin-electron model (PEM) when applied to the description of...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Some aspects of physical phenomena in high-Tc crystals caused by anharmonicity of the crystal lattice are discussed. Appropriate theoretical models
are considered. A review is given of the results obtained while investigating
the pseudospin-electron model (PEM) when applied to the description of
structural and dielectric instabilities, phase separations and bistability phenomena. The theoretical problems are analyzed arising in PEM when the
strong short-range correlations and electron transfer are taken into account
simultaneously. |
