New experimental data on the temperature dependence of the optical reflectivity of YBa 2 Cu 3 O 7 films are studied in the framework of strong electron–phonon interaction. It is shown that the normal state reflectivity in the far- and mid-infrared

Observed optical reflectivity in the infrared spectral region is compared with theoretical predictions in a strongly coupled electron–phonon system. Starting from a Frohlich Hamiltonian, the spectral functions and their temperature dependence are d

A multiliquid approach, based on free carriers with strong electron-phonon interaction, localized polaronic states near 0.15 eV, and a mid-infrared band at 0.5 eV, is applied to model the optical response of La{2-x}SrxCuO4. The normal state reflectan

Some YBCO ceramics have been found to exhibit hysteresis of the current/voltage, I/V, characteristics, which reveals at a certain current If greater than critical current Ic a transition with switch from one branch of the I/V curve to another. In pre
