Defects in correlated metals and superconductors
TLDR
In this paper, the effect of impurities on local charge and spin degrees of freedom in 1D antiferromagnetically correlated systems was investigated. But the results were limited to the Tc cuprate normal state, which is not soluble in 2 or 3 dimensions and so few exact results are known.Citations

Electrodynamics of correlated electron materials
TL;DR: In this article, the authors review studies of the electromagnetic response of various classes of correlated electron materials including transition metal oxides, organic and molecular conductors, intermetallic compounds with $d$- and $f$-electrons as well as magnetic semiconductors.

Progress and perspectives on electron-doped cuprates
TL;DR: In this paper, the authors summarized the current experimental status of electron-doped cuprates, with a goal to provide a snapshot of the current understanding of these materials, and synthesize this information into a consistent view on a number of topics important to both this material class as well as the overall cuprate phenomenology including the phase diagram, the superconducting order parameter symmetry, phase separation, pseudogap effects, the role of competing orders, the spin-density wave mean-field description of the normal state, and electron-phonon coupling.

Lattice symmetry breaking in cuprate superconductors: stripes, nematics, and superconductivity
TL;DR: In this paper, the authors give an overview of both theoretical and experimental developments concerning states with lattice symmetry breaking in the cuprate high-temperature superconductors. But the results obtained using the techniques of neutron and X-ray scattering and scanning tunnelling spectroscopy are not discussed.

TL;DR: Inelastic X-ray scattering studies of YBa2Cu3O6.6 reveal strong electron-phonon coupling and an inhomogeneous state made up of charge-density-wave nanodomains, which may explain some anomalous properties of the pseudogap state as mentioned in this paper.

Phase Transitions and Critical Phenomena
TL;DR: The field of phase transitions and critical phenomena continues to be active in research, producing a steady stream of interesting and fruitful results as discussed by the authors, and the major aim of this serial is to provide review articles that can serve as standard references for research workers in the field.
Journal ArticleDOI
Theory of Superconductivity
TL;DR: In this article, a theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the electrons states involved is less than the phonon energy, and it is favorable to form a superconducting phase when this attractive interaction dominates the repulsive screened Coulomb interaction.
