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

This article discusses fluctuating order in a quantum disordered phase proximate to a
quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies …

Electronic charges introduced in copper-oxide (CuO2) planes generate high-transition-
temperature (T c) superconductivity but, under special circumstances, they can also order …

Condensed matter is one of the most active areas of research in physics. Ev ery year new
materials are discovered with properties that are as challenging as or more than those of the …

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

The influence of quenched disorder on the competition between ordered states separated
by a first-order transition is investigated. A phase diagram with features resembling quantum …

The Hall coefficient RH of the cuprate superconductor YBa 2 Cu 3 O y was measured in
magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152 in the underdoped …

This review is an up-to-date snapshot of the current situation in studies of materials with
competing electron spectrum instabilities, namely Cooper pairing, on the one hand, and …

We report experimental evidence for the spatial variation of hole concentration x hole in the
high T c superconductor La 2− x Sr x CuO 4 (0.04≤ x≤ 0.16) via 63 Cu NQR using 63 Cu …

Abstract 63 Cu and 139 La nuclear quadrupole resonance and Zeeman perturbed nuclear
magnetic resonance experiments are performed on the striped phase of the high …
