The last decade witnessed significant progress in angle-resolved photoemission
spectroscopy (ARPES) and its applications. Today, ARPES experiments with 2-meV energy …

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 …

* Introducing a unique method to study the atomic structure of nano-materials* Award
winning research. Takeshi Egami received the 2003 Eugene Bertram Warren Diffraction …

Coupling between electrons and phonons (lattice vibrations) drives the formation of the
electron pairs responsible for conventional superconductivity. The lack of direct evidence for …

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 …

This article gives an overview of both theoretical and experimental developments
concerning states with lattice symmetry breaking in the cuprate high-temperature …

We report hard (14 keV) x-ray diffraction measurements on three compositions (x= 0.11,
0.12, 0.13) of the high-temperature superconductor La 2− x Sr x CuO 4. All samples show …

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 …

We review recent experimental and theoretical results on the interaction between single-
particle excitations and collective spin excitations in the superconducting state of high-Tc …

Formation of electron pairs is essential to superconductivity. For conventional
superconductors, tunnelling spectroscopy has established that pairing is mediated by …
