To provide a foundation for theoretical models of high-temperature superconductivity, experimental research has sought to establish correspondences between macroscopic transport coefficients on the one hand, and atomic-scale correlation functions measured by spectroscopic and scattering probes on the other hand. This research avenue has been confounded by the gradual onset of electronic ordering phenomena and of the corresponding transport anomalies. We report measurements of the uniaxial-stress dependence of the normal-state resistivity and Hall coefficient of the underdoped high-temperature superconductor YBa₂Cu₃O_6.67. We observe a remarkable correspondence between the differential stress responses of the transport coefficients and resonant X-ray diffraction features indicative of charge ordering, which parallels the phenomenology of classical charge-density-wave compounds. However, our observations imply that static charge order is not responsible for a sign reversal of the Hall coefficient, and suggest that the interplay with liquid-like, dynamical charge correlations is essential for the prominent transport anomalies in the underdoped cuprates.

为了为高温超导性的理论模型提供基础，实验研究一方面试图建立宏观输运系数与另一方面由光谱和散射探针测量的原子尺度相关函数之间的对应关系。逐渐出现的电子排序现象和相应的传输异常混淆了这一研究途径。我们报告了欠掺杂高温超导体 YBa ₂ Cu ₃ O _{6.67的常态电阻率和霍尔系数的单轴应力依赖性的测量结果}. 我们观察到传输系数的微分应力响应与指示电荷排序的共振 X 射线衍射特征之间存在显着的对应关系，这与经典电荷密度波化合物的现象学相似。然而，我们的观察表明静电荷顺序不是霍尔系数符号反转的原因，并表明与液体状动态电荷相关性的相互作用对于欠掺杂铜酸盐中显着的传输异常至关重要。
