Electronic Correlation Mapping: From Finite to Extended Systems

From the Back Cover Knowing the excitation characteristics of matter is decisive for the understanding of a variety of physical processes, which are of significant technological importance. This self-contained work is a coherent presentation of the quantum theory of correlated few-particle excitations in finite and extended electronic systems. The first volume introduces basic theoretical concepts and tools for dealing with few-body excited states. With this second volume, the author presents an up-to-date selection of applications. The topics covered range from two-particle correlation and excitations of atomic systems to correlated many-particle correlation and excitations of large molecules, metal clusters, solids, surfaces and alloys.From the Contents: Two-particle correlated excitations of atomic systems Spin-dependent, two-particle excitations Electron-electron interaction in large molecules and clusters Pair-correlation imaging in solids, surfaces and alloys Product Description An up-to-date selection of applications of correlation spectroscopy, in particular as far as the mapping of properties of correlated many-body systems is concerned. The book starts with a qualitative analysis of the outcome of the two-particle correlation spectroscopy of localized and delocalized electronic systems as they occur in atoms and solids. The second chapter addresses how spin-dependent interactions can be imaged by means of correlation spectroscopy, both in spin-polarized and extended systems. A further chapter discusses possible pathways for the production of interacting two-particle continuum states. After presenting some established ways of quantifying electronic correlations and pointing out the relationship to correlation spectroscopy, the author addresses in a separate chapter the electron-electron interaction in extended systems, and illustrates the ideas by some applications to fullerenes and metal clusters. The last two chapters are devoted to the investigation of the potential of two-particle spectroscopy in studying ordered surfaces and disordered samples. Throughout the book the material is analyzed using rather qualitative arguments, and the results of more sophisticated theories serve the purpose of endorsing the suggested physical scenarios. The foundations of some of these theories have been presented in a corresponding volume entitled "Concepts of Highly Excited Electronic Systems" (3-527-40335-3).
