We consider bosonic dipolar molecules in layered optical lattice and demonstrate possibility of formation of quantum rough flexible chains (perpendicular to the layers) by ab initio MC simulations. BKT transition into a stiff state for a single chain is observed. Results of preliminary J-current-type model simulations as well as of the bosonization analysis of multi-chain ensemble are discussed.
