AbstractUsing electronic states and phonon states from the first-principles calculations and including both conventional electron-phonon charge coupling and Jahn-Teller coupling, we predict T(c) and other superconducting properties. The only adjustable parameter in the theory is the screening length, R(sc). Using R(sc) = 0.8-1.0 Å, we find excellent agreement with experiment for T(c) (16-18 K), pressure dependence of T(c) (ΔT(c) = -6 to - 10 K for 1 GPa), and 12C to 13C isotope shift (α(C) = 0.2); experimental values: 19 K, -7 K, and 0.3, respectively .
