Strange metals possess highly unconventional electrical properties, such as a linear-in-
temperature resistivity,,,,–, an inverse Hall angle that varies as temperature squared,–and a …

The currently established electronic phase diagram of cuprates is based on a study of single-
and double-layered compounds. These CuO2 planes, however, are directly contacted with …

The enigmatic pseudogap phase in underdoped cuprate high-T c superconductors has long
been recognized as a central puzzle of the T c problem. Recent data show that the …

Electronic inhomogeneity appears to be an inherent characteristic of the enigmatic cuprate
superconductors. Here we report the observation of charge–density–wave correlations in …

To explore the doping dependence of the recently discovered charge-density-wave (CDW)
order in YBa 2 Cu 3 O y, we present a bulk-sensitive high-energy x-ray study for several …

In the quest to increase the critical temperature T c of cuprate superconductors, it is essential
to identify the factors that limit the strength of superconductivity. The upper critical field H c2 …

In the quest for superconductors with higher transition temperatures (T c), one emerging
motif is that electronic interactions favorable for superconductivity can be enhanced by …

High-temperature superconductivity, with transition temperatures up to≈ 134 K at ambient
pressure, occurs in layered cuprate compounds. The conducting CuO2 planes, which are …
