    Abstract

    We discuss phase diagrams obtained by calculating temperature-dependent correlation functions for superconductivity and density waves for a single (5,0) carbon nanotube (CN). We use one-loop renormalization group method within logarithmic accuracy. In this system we must specify scattering channels in terms of momentum along the circumferential direction as well as the axis direction, since (5,0) CN has two degenerate bands crossing the Fermi energy with circumferential momenta. We find singlet-superconducting phase with 5 ℏ circumferential angular momentum. Critical exponents for each correlation functions are also calculated.
