Superconductors with strong coupling -- Self-energy parts -- General properties of the Eliashberg equations -- Critical temperature -- Weak coupling -- Intermediate coupling ([lambda] [less-than, similar] 1.5) -- Coulomb interaction -- Very strong coupling -- Properties of superconductors with strong coupling -- Electron-phonon interaction and renormalization of normal parameters -- Nonlinear electron-phonon interactions -- Phonon dynamics of perovskites -- Anharmonicity -- Bipolaronic superconductivity and negative Hubbard U-models -- Isotope effect -- Experimental Methods -- Tunneling spectroscopy -- Experimental methods -- Energy gap and transition temperature -- Inversion of the gap equation and [alpha superscript 2]F([Omega]) -- Electron-phonon coupling parameter [lambda] -- Infrared spectroscopy -- Ultrasonic attenuation -- Nuclear magnetic resonance -- Electronic Mechanisms -- The Little model -- "Sandwich" excitonic mechanism -- Excitons and high T[subscript c] -- Three-dimensional systems -- Pairing of conduction electrons via interaction with localized states -- Two delocalized groups -- Negative U-centers -- Plasmons -- Overlapping bands. "Demons" -- Two-dimensional electron gas -- Coexistence of phonon and electronic mechanisms -- Magnetic Mechanisms Summary 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 temperature cuprates Analysis Superconductivity Bibliography Includes bibliographical references (pages 166-178) and index Notes English Print version record Subject Superconductivity.
