- W1983166587 abstract "High-resolution measurements of superfluid density ${ensuremath{rho}}_{s}(T)$ and broadband quasiparticle conductivity ${ensuremath{sigma}}_{1}(ensuremath{Omega})$ have been used to probe the low-energy excitation spectrum of nodal quasiparticles in underdoped ${text{YBa}}_{2}{text{Cu}}_{3}{text{O}}_{6+y}$. Penetration depth $ensuremath{lambda}(T)$ is measured to temperatures as low as 0.05 K. ${ensuremath{sigma}}_{1}(ensuremath{Omega})$ is measured from 0.1 to 20 GHz and is a direct probe of zero-energy quasiparticles. The data are compared with predictions for a number of theoretical scenarios that compete with or otherwise modify pure ${d}_{{x}^{2}ensuremath{-}{y}^{2}}$ superconductivity, in particular, commensurate and incommensurate spin and charge-density waves; ${d}_{{x}^{2}ensuremath{-}{y}^{2}}+is$ and ${d}_{{x}^{2}ensuremath{-}{y}^{2}}+i{d}_{xy}$ superconductivity; circulating current phases; and the BCS-BEC crossover. We conclude that the data are consistent with a pure ${d}_{{x}^{2}ensuremath{-}{y}^{2}}$ state in the presence of a small amount of strong scattering disorder, and are able to rule out most candidate competing states either completely or to a level set by the energy scale of the disorder, ${T}_{d}ensuremath{sim}4text{ }text{K}$. Commensurate spin and charge-density orders, however, are not expected to alter the nodal spectrum and therefore cannot be excluded." @default.
