Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to
elucidate the nature of the electronic interactions that cause pairing. Superconductivity …

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 …

Infinite-layer Nd 1− x Sr x NiO 2 thin films with Sr do** level x from 0.08 to 0.3 are
synthesized and investigated. We find a superconducting dome x between 0.12 and 0.235 …

The perfectly linear temperature dependence of the electrical resistivity observed as T→ 0 in
a variety of metals close to a quantum critical point,,–is a major puzzle of condensed-matter …

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 three central phenomena of cuprate (copper oxide) superconductors are linked by a
common do** level p*—at which the enigmatic pseudogap phase ends and the resistivity …

An understanding of the high-temperature copper oxide (cuprate) superconductors has
eluded the physics community for over thirty years and represents one of the greatest …

Inelastic light scattering is an intensively used tool in the study of electronic properties of
solids. Triggered by the discovery of high-temperature superconductivity in the cuprates and …

The presence or absence of a quantum critical point and its location in the phase diagram of
high-temperature superconductors have been subjects of intense scrutiny. Clear evidence …

The origin of the exceptionally strong superconductivity of cuprates remains a subject of
debate after more than two decades of investigation. Here we follow a new lead: The onset …
