Springer Many-Body Approach to Electronic Excitations Book

Master the many-body-theoretical basis of theoretical spectroscopy with this advanced text from Springer. This book provides a unified look at the applications of spectroscopy in condensed matter, covering essential areas such as crystals, nanosystems, and molecules. Designed for a wide range of readers, this resource serves everyone from graduate students to active researchers in the field. The theory is built from first principles, providing a deep understanding of electron-electron and spin interactions. By utilizing many-body perturbation theory, a quantum-field-theoretical description, and Green's functions, the text offers a rigorous framework for studying complex systems. Readers will find clear explanations of important expressions for ground states, as well as electronic single-particle and pair excitations. This volume is an essential addition to the Springer Series in Solid-State Sciences, offering the technical depth required for modern research in physical chemistry and condensed matter physics.
