Abstract:
A simple description has been proposed for the renormalization of the conduction band parameters in cuprates owing to the interaction of the current carriers with phonons. Kinks in the quasiparticle dispersion law in the optical phonon mode region ($70$ meV, compound Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8-x}$ and data on the temperature dependence of the superconducting current density in YBa$_{2}$Cu$_{3}$O$_{7}$ have been analyzed. Ideas of new experiments have been discussed.
