The percolation limit for stripe correlations in cuprates and the onset of strange-metal behavior

ORAL

Abstract

A variety of measurements on La2-xSrxCuO4 and related cuprates can be interpreted consistently in terms spin and charge stripe correlations that percolate across the CuO2 planes at lower hole concentrations p, but reach a percolation threshold at p ~ 0.19 [1]. Beyond this point, regions with quasiparticles percolate within and between the planes. The impact of scattering from the residual stripe patches likely contributes to the observed strange-metal behavior at p > 0.19 [1]. The data supporting this perspective, and the role of intrinsic disorder, will be discussed.
