Electron-Electron Correlation Effects in Low-Dimensional Conductors and Superconductors

This volume presents lectures on new approaches to electron-electron and electron-phonon correlation effects in low-dimensional materials: organic solids, conducting polymers such as polyacetylenes (CH)x, organic and copper-oxide superconductors with high Tc values. Researchers in the fields of solid state physics and superconductivity will find this collection of papers particularly useful.
