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 …

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

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

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 …

We probe the collective magnetic modes of La 2 CuO 4 and underdoped La 2-x Sr x CuO 4
(LSCO) by momentum resolved resonant inelastic x-ray scattering (RIXS) at the Cu L 3 …

The effect of Lifshitz transition on thermodynamics and superconductivity in hole-doped
cuprates has been heavily debated but remains an open question. In particular, an observed …

High-temperature superconductivity in the copper-oxide ceramics remains an unsolved
problem because we do not know what the propagating degrees of freedom are in the …

We use cluster dynamical mean-field theory to study the simplest models of correlated
electrons, the Hubbard model and the tJ model. We use a plaquette embedded in a medium …

The metal-insulator transition and unconventional metallic transport in vanadium dioxide
(VO 2) are investigated with a combination of spectroscopic ellipsometry and reflectance …

Cuprate high-T c superconductors exhibit enigmatic behavior in the nonsuperconducting
state. For carrier concentrations near “optimal doping”(with respect to the highest T cs) the …
