Extending the Luttinger liquid theory to incorporate trigonal warping and chirality effects, we derive the current contribution $I_e$ {\sl even} in the applied voltage $V$ and {\sl odd} in an orbital magnetic field $B$, which is non-zero only for chiral tubes and in the presence of interactions.4 pages, 1 figure, minor changes, to appear in PRLMesoscale and Nanoscale PhysicsStrongly Correlated Electronstext
