Modulation of the plasma frequency in cuprate superconductors with of the active CuO2 planes

Abstract

In this article we consider the modulation of the plasma frequency switching current-phase dependence of Josephson systems based on the CuO2 harmonic mode into the anharmonic one. It is established the increase of the plasma frequency in the cuprate high-temperature superconductors arising due to deviation of dependence current-phase between the oxide planes in high-temperature superconductors from the standard sine wave form.
