<b>Jamal Berakdar</b> is an outstanding young researcher who has accomplished in less than ten years remarkable contributions to the field. He is well acknowledged by the scientific community.<br /> PhD-thesis at University of Freiburg (Prof. Klar, 1994), Humboldt- and Research fellow at Atomic & Molecular Physics Laboratories, Australian National University; since 1998 researcher at Max-Planck Institute for Microstructure Physics in Halle, Germany.

Knowledge of the excitation characteristics of matter is decisive for the descriptions of a variety of dynamical processes, which are of significant technological interest. E.g. transport properties and the optical response are controlled by the excitation spectrum. <p>This self-contained work is a coherent presentation of the quantum theory of correlated few-particle excitations in electronic systems. It begins with a compact resume of the quantum mechanics of single particle excitations. Methods are then presented for the treatment of few-particle excitations and scattering states in finite and extended systems. Particular emphasis is put on the Green's function technique, which offers a natural tool to unravel the relationship between the physics of small and large electronic systems. The book contains explicit expressions for the Coulomb Green's function of two charged particles and a generalization to few-body compounds. Green's function techniques are utilized as a systematic approach for the treatment of multi-particle excitations in extended systems.</p> <p>A complimentary volume presents an up-to-date selection of applications of the developed concepts and a comparison with available experiments.</p> <p><b>Contents:</b></p> <ul> <li>Introduction and basic concepts</li> <li>Two-particle Coulomb systems</li> <li>Resonant and non-resonant two-particle excitations</li> <li>Multi-particle excited states in finite electronic systems</li> <li>Excitations in extended electronic systems</li> </ul>
