Abstract

We explore the nature of anomalous conduction of wave packets in disorder-free incommensurate multiwalled carbon nanotubes. The spectrum-averaged diffusion exponent is obtained by calculating the multifractal dimension of the energy spectrum. Depending on the shell chirality, the exponent is found to lie within the range 1/2<=eta<1. For large unit-cell mismatch between incommensurate shells, eta ...
