Abstract:
Simple analytic closed-expression scaling functions are reported for the lambda transition of confined liquid 4He in equilibrium. The results follow directly from the quantization of the fluctuation modes of the order parameter and exhibit a smooth temperature dependence down to a shifted transition temperature.
