Kinematics of Persistent Currents in Nanotubes and Tori -Time-reversal symmetric gauge field and its application-

Abstract

The basic properties of conducting electrons in carbon nanotubes are reviewed from a theoretical perspective, and studies performed on persistent currents in toroidal carbon nanotubes and on the local energy gap in deformed nanotubes are reported on.Comment: 7 pages, 5 figs, invited talk at the 28th International Conference of Theoretical Physics, Electron Correlations in Nano and Macrosystems, Sep 2004, Polan
