Owing to its unique geometry, the kagome lattice hosts various many-body quantum states
including frustrated magnetism, superconductivity, and charge-density waves (CDWs). In …

The principal purpose of this topical review is to single out some of the universal features of
high-temperature (high-T c) and related strongly-correlated systems, which can be …

A long-standing problem in the study of the under-hole-doped cuprates has been the
description of the Fermi surfaces underlying the high magnetic field quantum oscillations …

Collective spin excitations in magnetically ordered crystals, called magnons or spin waves,
can serve as carriers in novel spintronic devices with ultralow energy consumption. The …

The interpretation of how superconductivity disappears in cuprates at large hole do** has
been controversial. To address this issue, we present an experimental study of single-crystal …

The nature of the normal state of cuprate superconductors continues to stimulate
considerable speculation. Of particular interest has been the linear temperature …

BaNi 2 As 2 is a nonmagnetic analog of the iron pnictide superconductors, and exhibits an
incommensurate charge density wave (IC-CDW) and a sizable elastoresistance. In this …

Thanks to high resolution and polarization analysis, resonant inelastic x-ray scattering
(RIXS) magnetic spectra of La 2 CuO 4, Sr 2 CuO 2 C l 2 and CaCuO 2 reveal a rich set of …

Estimating many-body effects that deviate from an independent particle approach has long
been a key research interest in condensed matter physics. Layered cuprates are prototypical …

We provide a unified interpretation of both paramagnon and plasmon modes in high-T c
copper-oxides, and verify it quantitatively against available resonant inelastic x-ray …
