Abstract

Superconductivity of a double chain superconductor Pr2 Ba4 Cu7 O15 - δ is investigated on the double chain Hubbard model with realistic values of the hopping parameters, on-site interaction U, and off-site interaction V. By applying the fluctuation exchange (FLEX) method to the model and solving the linearized Eliashberg's equation, singlet pairing superconducting phase, which has the doping dependence of Tc consistent with the experimental results, is obtained. The finite temperature quantum Monte Carlo (FTQMC) calculation also supports the FLEX results at least qualitatively.
