Gauge approach to superfluid density in underdoped cuprates
arXiv:1501.03531 · doi:10.1209/0295-5075/110/37001
Abstract
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.
