The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

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

Conventional superconductivity emerges from pairing of charge carriers—electrons or holes—
mediated by phonons. In many unconventional superconductors, the pairing mechanism is …

The idea of superconductivity without the mediating role of lattice vibrations (phonons) has a
long history. It was realized soon after the publication of the Bardeen–Cooper–Schrieffer …

In the copper oxide parent compounds of the high-transition-temperature superconductors
the valence electrons are localized—one per copper site—by strong intra-atomic Coulomb …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

Unravelling competing orders emergent in doped Mott insulators and their interplay with
unconventional superconductivity is one of the major challenges in condensed matter …

Recent transport experiments in the original cuprate high temperature superconductor, La
2− x Ba x CuO 4, have revealed a remarkable sequence of transitions and crossovers that …

Martensitic transformations are diffusionless, solid-to-solid phase transitions, and have been
observed in metals, alloys, ceramics and proteins,. They are characterized by a rapid …

Unidirectional (“stripe”) charge density wave order has now been established as a
ubiquitous feature in the phase diagram of the cuprate high-temperature superconductors …
