A review of the loop algorithm, its generalizations, and its relation to some other Monte Carlo
techniques is given. The loop algorithm is a quantum Monte Carlo procedure that employs …

We report on the phase diagram for charge-stripe order in La 1. 6− x Nd 0.4 Sr x CuO 4,
determined by neutron and x-ray scattering studies and resistivity measurements. From an …

The spin dynamics of an arbitrary localized impurity in an insulating two-dimensional
antiferromagnet, across the host transition from a paramagnet with a spin gap to a Néel …

We present the universal theory of arbitrary, localized impurities in a confining paramagnetic
state of two-dimensional antiferromagnets with global SU (2) spin symmetry. The energy gap …

We present the results of neutron-scattering studies on various aspects of crystalline and
magnetic structure in single crystals of La 1.6− x Nd 0.4 Sr x CuO 4 with x= 0.12 and 0.15. In …

It is argued that the electron stripes as found in correlated oxides have to do with an
unrecognized form of order. The manifestation of this order is the robust property that the …

One of the major themes in correlated electron physics over the last quarter century has
been the problem of high-temperature superconductivity in hole-doped copper-oxide …

We use a number of large-N limits to explore the competition between ground states of
square lattice doped antiferromagnets which break electromagnetic U (1), time-reversal, or …

Recent improvements in instrumentation have established resonant inelastic X-ray
scattering (RIXS) as a valuable new probe of the magnetic excitations in the cuprates. This …

Using a spin-only model, we compute spin excitation spectra in a bond-centered stripe state
with long-range magnetic order. We employ a bond operator formalism, which naturally …
