The author reviews some of the important successes achieved by Eliashberg theory in
describing the observed superconducting properties of many conventional superconductors …

In narrow-band systems electrons can interact with each other via a short-range nonretarded
attractive potential. The origin of such an effective local attraction can be polaronic or it can …

In our Lecture we take the opportunity to describe the guiding ideas and our effort in the
search for high-T, superconductivity. They directed the way fromthe cubic niobium …

This is a revised version of the first edition published in 1991. At the same time, this is a
revised version of the Syokabo edition, which was written in Japanese and published in …

The capacity C of a communication channel is the maximum rate at which information can
be transmitted without error from the channel's input to its output. The authors review …

Electronic energy bands calculated from local-density-functional (LDF) theory are used to
predict anisotropic transport properties of the oxide superconductors La 2− x Sr x CuO 4 and …

The case is made that the spin-liquid state of a Mott insulator, hypothesized to exist by
Anderson and identified by him as the correct context for discussing high-temperature …

We present a theory of Raman scattering in the Hubbard model. The scattering of light has
two contributions. One gives rise to scattering by spin degrees of freedom in the insulating …

The results of a systematic study of the optical properties of the YBa 2 Cu 3 O 6+ x-based
insulators and superconductors are reported. Specifically, we present measurements and …

Using polarized reflectivity measurements of single-domain crystals, we are able to
distinguish chain and plane contributions to the infrared conductivity of YBa 2 Cu 3 O 7. A …
