The concepts of the Jahn-Teller effect and vibronic coupling are being
applied to more and more systems in both chemistry and physics. Aspects
of structural chemistry such as the distortion of the nuclear framework
to a lower-symmetry conformation have received an increasing attention,
as well as the dynamics on the coupled potential energy surfaces.
The Jahn-Teller intersections are now recognized as prototype cases of
conical intersections where the nuclear motion is known to be inherently
nonadiabatic in nature and interchanges freely between the different
potential energy surfaces. In the condensed phase especially, the
significance of the Jahn-Teller effect has been increasingly
appreciated, following the discovery of superconductivity in the
fullerides and of very large ("colossal") magnetoresistance in the
manganite perovskites. Indeed, these materials are particularly
challenging since the Jahn-Teller interaction competes with electronic
correlation effects.
Vibronic Interactions and the Jahn-Teller Effect: Theory and
Applications provides an in-depth discussion of the Jahn-Teller effect
and vibronic interactions as reflected by the contributions presented at
the XX International Conference on the Jahn-Teller effect, Fribourg,
Switzerland, 2010. The following topics have been treated in a clear and
concise way:
- Complex topologies of Jahn-Teller effect and conical intersections
- Multi-state vibronic interactions on strongly coupled potential energy
surfaces
- Interplay of vibronic and spin-orbit coupling
- Strain in Jahn-Teller systems and cooperative Jahn-Teller effect
- Orbital ordering and its relation to ferromagnetism, ferroelectricity
and molecular magnets
- The Jahn-Teller effect in icosahedral systems
- The Jahn-Teller effect and high temperature superconductivity
This book is of interest to a wide audience including academic and
industrial theoretical and experimental physicists, chemists,
spectroscopists, and crystallographers.
