Query: Theory of Chiral Transport in Carbon Nanotubes   Based on the similarity between the chiral nanotube and the classical
solenoid, we study chiral transport along the circumferential direction in a
carbon nanotube. We calculate the chiral conductivity, representing a
circumferential current induced by an electric field along the nanotube axis
for various chiralities of carbon nanotubes. We find that the chiral
conductivity in a chiral nanotube is in general non zero, and oscillates as a
function of the Fermi energy. This oscillating behavior is attributed to the
subband structure of the nanotubes and the warping of the Fermi surfaces.
