The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

Weak-coupling approaches to the pairing problem in the iron pnictide superconductors have
predicted a wide variety of superconducting ground states. We argue here that this is due …

Recently developed numerical methods have enabled the explicit construction of the
superconducting state of the Hubbard model of strongly correlated electrons in parameter …

Theories based on the coupling between spin fluctuations and fermionic quasiparticles are
among the leading contenders to explain the origin of high-temperature superconductivity …

We present new x-ray and neutron-scattering measurements of stripe order in La 1.875 Ba
0.125 CuO 4, along with low-field susceptibility, thermal conductivity, and specific-heat data …

There is growing evidence that the hole-doped single-band Hubbard and t− J models do not
have a superconducting ground state reflective of the high-temperature cuprate …

The energetics of the interplay between superconductivity and the pseudogap in high-
temperature superconductivity is examined using the eight-site dynamical cluster …

An understanding of the effects of electronic correlations in quantum systems is one of the
most challenging problems in physics, partly due to the relevance in modern high …

We review the intermediate coupling model for treating electronic correlations in the
cuprates. Spectral signatures of the intermediate coupling scenario are identified and used …
