摘要：

We prove that a gauge approach based on a composite structure of the hole in hole-doped cuprates is able to capture analytically many features of the experimental data on superfluid density in the moderate underdoping to nearly optimal doping region, including critical exponent, the Uemura relation and near-universality of the normalized superfluid density.
