X-ray techniques have been used for more than a century to study the atomic and electronic
structure in practically any type of material. The advent of correlated electron systems, in …

The electronic phase diagrams of many highly correlated systems, and, in particular, the
cuprate high temperature superconductors, are complex, with many different phases …

The pseudogap is a partial gap in the electronic density of states that opens in the normal
(non-superconducting) state of cuprate superconductors and whose origin is a long …

The presence of different electronic orders other than superconductivity populating the
phase diagram of cuprates suggests that they might be the key to disclose the mysteries of …

The existence of electronic symmetry breaking in the underdoped cuprates and its
disappearance with increased hole density p are now widely reported. However, the relation …

A long-standing problem in the study of the under-hole-doped cuprates has been the
description of the Fermi surfaces underlying the high magnetic field quantum oscillations …

In the underdoped regime, the cuprate high-temperature superconductors exhibit a host of
unusual collective phenomena, including unconventional spin and charge density …

Fluctuating superconductivity—vestigial Cooper pairing in the resistive state of a material—
is usually associated with low dimensionality, strong disorder, or low carrier density. Here …
