We report measurements of the specific heat near the superfluid transition of 4He confined in uniform channels of 1 μm square cross-section. This system undergoes a crossover from three dimensional behavior (3D) to 1D as the transition is approached. This results in a substantial rounding of the specific heat maximum as well as a shift to colder temperatures relative to the bulk system. We compare these data to previous measurements where crossovers from 3D to 2D and 0D were studied with the… CONTINUE READING
