The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

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

A two-dimensional electronic system forms at the interface between the band insulators,
LaAlO3 and SrTiO3. Samples fabricated until now have been found to be either magnetic or …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

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

Abstract Superconductivity was recently observed,,,,,, in iron-arsenic-based compounds with
a superconducting transition temperature (T c) as high as 56 K, naturally raising …

In the Kondo insulator samarium hexaboride (SmB6), strong correlation and band
hybridization lead to an insulating gap and a diverging resistance at low temperature. The …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

Evidence is mounting that charge order competes with superconductivity in high T c
cuprates. Whether this has any relationship to the pairing mechanism is unknown as neither …

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 …
