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

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 …

The authors discuss concepts used by them and others for studying high temperature
superconductivity. These shed some light on basic questions. Suggestions are presented …

Superconductivity in layered copper oxide compounds emerges when charge carriers are
added to antiferromagnetically ordered CuO2 layers. The carriers destroy the …

Linear response theory, commonly known as the random-phase approximation (RPA),
predicts a rich magnetic excitation spectrum for d-wave superconductors. Many of the …

Neutron scattering studies have provided important information about the momentum and
energy dependence of magnetic excitations in cuprate superconductors. Of particular …

We calculate the expected finite frequency neutron-scattering intensity based on the two-
sublattice collinear antiferromagnet found by recent neutron-scattering experiments as well …

We have measured the spin fluctuations in the YBa 2 Cu 3 O 6.5 (YBCO 6.5, T c= 59 K)
superconductor at high-energy transfers above∼ 100 meV. Within experimental error, the …

Using polarized neutron scattering we establish that the magnetic order in La 1.48 Nd 0.4 Sr
0.12 CuO 4 is either (i) one dimensionally modulated and collinear, consistent with the stripe …

We study the spin excitation spectra of the two-dimensional spin-1 2 Heisenberg model with
a checkerboard structure using stochastic analytic continuation of the imaginary-time …
