This article reviews the physics of high-temperature superconductors from the point of view
of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed …

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 …

ONE of the long-standing mysteries associated with the high-temperature copper oxide
superconductors concerns the anomalous suppression1 of superconductivity in La2 …

I reexamine the work of Hertz on quantum phase transitions in itinerant fermion systems. I
determine when it is permissible to integrate out the fermions and analyze the critical …

Scanning tunneling spectroscopy of the high-T c superconductor Bi2Sr2CaCu2O8+
δreveals weak, incommensurate, spatial modulations in the tunneling conductance. Images …

Previously we have presented evidence for stripe order of holes and spins in La 1. 6− x Nd
0.4 Sr x CuO 4 with x= 0.12. Here we show, via neutron diffraction measurements of …

We present a neutron diffraction study of charge and spin order within the CuO 2 planes of
La 1.48 Nd 0.4 Sr 0.12 CuO 4, a crystal in which superconductivity is anomalously …

We calculate the fermion Green function and particle-hole susceptibilities for a degenerate
two-dimensional fermion system with a singular gauge interaction. We show that this is a …

The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the
density of states (dos) on electronic properties. More importantly, it appears to play a major …

We present a neutron scattering study of stripe correlations measured on a single crystal of
La 1.875 Ba 0.125 CuO 4. Within the low-temperature-tetragonal (LTT) phase, superlattice …
