Self-generated electronic heterogeneity and quantum glassiness in the high-temperature superconductors
Self-generated electronic heterogeneity and quantum glassiness in the high-temperature superconductors
We present a systematic study of the spin and charge dynamics of copper oxide superconductors as a function of carrier concentration $x$. Our results portray a coherent physical picture, which reveals a quantum critical point at optimum doping $(x={x}_{\mathit{opt}})$, and the formation of a glassy state at $x<{x}_{\mathit{opt}}$. This mechanism …
