The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

In the cuprates, one-dimensional (1D) chain compounds provide a distinctive opportunity to
understand the microscopic physics, owing to the availability of reliable theories. However …

This article reviews the physics of high-temperature superconductors from the point of view
of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed …

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 …

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 …

In normal metals, macroscopic properties are understood using the concept of
quasiparticles. In the cuprate high-temperature superconductors, the metallic state above …

Establishing a minimal microscopic model for cuprates is a key step towards the elucidation
of a high-T c mechanism. By a quantitative comparison with a recent in situ angle-resolved …

Oxygen vacancies created in anatase TiO 2 by UV photons (80–130 eV) provide an effective
electron-doping mechanism and induce a hitherto unobserved dispersive metallic state …

Although nineteen years have passed since the discovery of high temperature cuprate
superconductivity, there is still no consensus on its physical origin. This is in large part …
