Abstract:	The transition from a magnetic field-tuned spin Luttinger-liquid with algebraic spin correlations to a Bose-Einstein Condensate of magnons with long-range magnetic order is investigated in the two-leg spin ladder material bis(piperidinium)tetrabromocuprate(II) (C5H12N)2CuBr4. By neutron diffraction and measurements of the magnetocaloric effect we show that the ordering temperature, transverse and longitudinal magnetizations, and critical behavior are highly dominated by the tunable one-dimensional physics of the weakly-coupled spin Luttinger-liquids. Our experimental results are in excellent agreement with theoretical calculations with renormalized mean-field interaction parameters.
