We report hard (14 keV) x-ray diffraction measurements on three compositions (x= 0.11, 0.12, 0.13) of the high-temperature superconductor La 2− x Sr x CuO 4. All samples show …
The nature of the pseudogap phase of the copper oxides ('cuprates') remains a puzzle. Although there are indications that this phase breaks various symmetries, there is no …
We propose that resistivity curvature mapping (RCM) based on the in-plane resistivity data is a useful way to objectively draw electronic phase diagrams of high-T c cuprates, where …
Recent transport experiments in the original cuprate high temperature superconductor, La 2− x Ba x CuO 4, have revealed a remarkable sequence of transitions and crossovers that …
In many unconventional superconductors, the presence of a pseudogap—a suppression in the electronic density of states extending above the critical temperature—has been a long …
The large variations in T c across the cuprate families is one of the major unsolved puzzles in condensed matter physics and is poorly understood. Although there appears to be a great …
High resolution angle-resolved photoemission spectroscopy data along the (0, 0)-(π, π) nodal direction with significantly improved statistics reveal fine structure in the electron self …
Quantum phase transitions play an important role in shaping the phase diagram of high- temperature cuprate superconductors. These cuprates possess intertwined orders which …

By measuring the Hall coefficient RH up to 1000 K in La 2 Cu O 4, Pr 1.3 La 0.7 Cu O 4, and La 2− x Sr x Cu O 4 (LSCO), we found that the temperature (T) dependence of RH in LSCO …
