Abstract

Recently Chakravarty, Laughlin, Morr, and Nayak [Phys. Rev. B 62, 4880 (2000)] made an interesting proposal that the cuprate superconductors possess a hidden “d-density-wave” (DDW) order. We study the implication of this proposal for the superfluid density ρ_s. We find that it predicts a temperature gradient |dρ_s/dT|_T=0 that is strongly doping dependent near the critical doping at which the superconducting gap vanishes. This demonstrates that the DDW scenario is inconsistent with existing well-established experimental data.
