We study the non-Ohmic current-voltage characteristics for the tunneling into fractional quantum Hall liquids in terms of chiral Tomonaga-Luttinger liquid (TLL) theory. Generalizing a model proposed by Lee and Wen, we investigate the effects of interaction between the charge and neutral modes. For small we found that the chiral TLL model could successfully explain the observed approximate dependence ().
