The discovery of high-temperature superconductivity in the copper oxides in 1986 triggered
a huge amount of innovative scientific inquiry. In the almost three decades since, much has …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Magic-angle twisted trilayer graphene (MATTG) has emerged as a moiré material that
exhibits strong electronic correlations and unconventional superconductivity,. However …

Geometrically frustrated kagome lattices are raising as novel platforms to engineer
correlated topological electron flat bands that are prominent to electronic instabilities. Here …

Charge density wave (CDW) orders in vanadium-based kagome metals have recently
received tremendous attention, yet their origin remains a topic of debate. The discovery of …

Superconductivity often emerges in the proximity of, or in competition with, symmetry-
breaking ground states such as antiferromagnetism or charge density waves,,,,(CDW). A …

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 …

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

We report the results of a comprehensive study of charge-density wave (CDW) correlations
in untwinned YBa 2 Cu 3 O 6+ x single crystals with 0.4≤ x≤ 0.99 using Cu L 3 edge …

During the past few decades, several new classes of superconductors have been
discovered that do not appear to be related to traditional superconductors. The source of the …
