SOLUTIONS FOR THE HIGHER-GRADE HYBRID MODEL OF LAYERED SUPERCONDUCTORS

摘要

A class of basic solutions for a model of layered superconductors is constructed. The considerations are based on the higher-grade hybrid model, constructed in the previous paper. In particular, for any range K of the Josephson interlayer couplings, we determine the spectrum of excited states with respect to all types of ground states calculated there for an infinite uniform superconductor. We discuss also solutions for a finite number of layers with periodic boundary conditions. In this way, instances of the amplitude-modulated solutions for the infinite stack of layers are found.
