Mechanisms of conventional and high Tc superconductivity /

Presents the methods, established results, and advances in the field of superconductivity including phonic, magnetic, and electronic models. The authors focus on the phenomenon of induced superconductivity in the high-temperature ("high-Tc") oxides, particularly the high transition tempera...
