| contents | We image local superfluid density in single crystals of Pd-intercalated ErTe$_3$ below the superconducting critical temperature, $T_c$, well below the onset temperature, $T_{CDW}$, of (disordered) charge-density-wave order. We find no detectable inhomogeneities. We observe a rapid increase of the superfluid density below $T_c$, deviating from the behavior expected in conventional Bardeen-Cooper-Schrieffer, and show that the temperature dependence is qualitatively consistent with a combination of quantum and thermal phase fluctuations. |
