Abstract

Using a simple model, the coexistence of superconductivity (SC) and the Jahn-Teller (JT) effect are studied for high-T c cuprate systems. The interplay of SC and JT gaps is studied and found that in the coexistence phase the SC gap as well as the JT gap are suppressed. For calculations, the single particle Green’s function technique of Zubarev is used. The density of states (DOS) and dispersion curves are also studied in the coexistence phase.
