ALKALI-DOPED FULLERIDES
Narrow-Band Solids with Unusual Properties

by Olle Gunnarsson (Max-Planck-Institut für Festkörperforschung, Germany)

Alkali-doped fullerides have attracted strong interest since their production became possible about fifteen years ago. This book presents recent work which may solve intriguing problems arising from a variety of remarkable properties. For example, these solids are superconductors with high transition temperatures, although the similarity between the electronic and phonon energy scales should suppress superconductivity. Moreover, the Ioffe–Regel condition for electrical conductivity is strongly violated. The book shows why superconductivity is nevertheless possible, owing to a local pairing mechanism. The Ioffe–Regel condition is derived quantum-mechanically, and it is explained why the underlying assumptions are violated for fullerides and high-Tc cuprates, for example. The book treats electronic and transport properties, reviewing theoretical and experimental results. It focuses on superconductivity, electrical conductivity and metal–insulator transitions, emphasizing the electron–electron and electron–phonon interactions as well as the Jahn–Teller effect.


Contents:

  • Structural Properties
  • Models and Parameters
  • Phonons and Electron–Phonon Coupling Strength
  • Interacting Electron–Phonon System
  • Electronic Structure
  • Plasmons
  • Metal–Insulator Transition
  • Electrical Resistivity

Readership: Graduate students and researchers in condensed matter physics.


“This book by Olle Gunnarsson provides a well-written and thoughtfully constructed account of the present state of our knowledge and will undoubtedly catalyse new studies which must result in not only the development of new understanding of superconductivity but the discovery of novel dynamic behaviour in systems which possess unique electronic and vibrational properties. This book is a lucid overview written by an expert researcher with a clear and deep understanding of a complex subject.”
