Evidence for stripe correlations of spins and holes in copper oxide superconductors
ONE of the long-standing mysteries associated with the high-temperature copper oxide superconductors concerns the anomalous suppression1 of superconductivity in La2-xBaxCuO4 (and certain related
Neutron Scattering with a Triple-Axis Spectrometer
Neutron scattering is an extremely powerful tool in the study of elemental excitations in condensed matter. This book provides a practical guide to basic techniques using a triple-axis spectrometer.
How to detect fluctuating stripes in the high-temperature superconductors
We discuss fluctuating order in a quantum disordered phase proximate to a quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies for extracting information

Colloquium : Theory of intertwined orders in high temperature superconductors
Understanding high temperature superconductors is a central problem in condensed matter physics. Many experiments have uncovered ordering tendencies which are responsible for the complex phase
Stripe Order in Superconducting La2−xBaxCuO4 (0.095 x 0.155)
The correlations between stripe order, superconductivity, and crystal structure in La{sub 2-x}Ba{sub x}CuO{sub 4} single crystals have been studied by means of x-ray and neutron diffraction as well
Quantum magnetic excitations from stripes in copper oxide superconductors
The results support the concept that stripe correlations are essential to high-transition-temperature superconductivity, and find that the observed spectrum can be understood within a stripe model by taking account of quantum excitations.
The Physics of Pair-Density Waves: Cuprate Superconductors and Beyond
We review the physics of pair-density wave (PDW) superconductors. We begin with a macroscopic description that emphasizes order induced by PDW states, such as charge-density wave, and discuss related
Coexistence of, and Competition between, Superconductivity and Charge-Stripe Order in La 1.6-x Nd 0.4 Sr x CuO 4
Previously we have presented evidence for stripe order of holes and spins in La{sub 1.6-x}Nd{sub 0.4}Sr{sub x}CuO{sub 4} with x=0.12. Here we show, via neutron diffraction measurements of magnetic
Dynamical layer decoupling in a stripe-ordered high-T(c) superconductor.
It is proposed that the Josephson coupling between near neighbor planes, especially in a crystal with the special structure of La(2-x)Ba(x)CuO(4), vanishes identically, and is the underlying cause of the dynamical decoupling of the layers recently observed in transport measurements at x = 1/8.
