Superfluid Density in the d -Density-Wave Scenario
Journal Article

· Physical Review Letters
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 {rho}{sub s}. We find that it predicts a temperature gradient vertical bar d{rho}{sub s}/dT vertical bar{sub 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.
