An experimental realization of a bosonic Luttinger liquid may possibly be found by confining helium-4 to narrow nanopores with large aspect ratios. We have employed worm algorithm path integral quantum Monte Carlo methods to study low dimensional, strongly interacting bosonic systems at finite temperature in the grand canonical ensemble. An analysis of the resulting numerical data indicates corrections to the scaling predictions of the usual harmonic Luttinger Liquid theory that can be understood by extending the field theory to include formally irrelevant operators.
