The competition between intertube hopping processes and density-densityinteractions is investigated in one-dimensional quantum dipolar bosons systemsof N coupled tubes at zero temperature. Using a phenomenological bosonizationapproach, we show that the resulting competition leads to an exotic quantumphase transition described by a U(1) x Z_N conformal field theory with afractional central charge. The emerging Z_N parafermionic critical degrees offreedom are highly nontrivial in terms of the original atoms or polar moleculesof the model. We further determine the main physical properties of the quantumcritical point in a double-tube system which has central charge c=3/2. Intriple-tube systems, we show that the competition between the two antagonisticprocesses is related to the physics of the two-dimensional Z_3 chiral Pottsmodel. This work opens the possibility to study the exotic properties of theZ_N parafermions in the context of ultracold quantum Bose gases.
