Abstract

We report detailed thermodynamic and transport measurements for nonsuperconducting La_1.7Sr_0.3CuO₄. Collectively, these data support the presence of a highly correlated Fermi-liquid ground state in La_2\ensuremath-xSr_xCuO₄ beyond the superconducting dome, and imply that charge transport in the cuprates is dominated at finite temperatures by electron-electron scattering.
