With a comprehensive discussion of the basic concepts and quantum mechanical fundamentals, this updated and extended third edition moves on to show how DMT can be used to describe processes in atomic and molecular physics with a minimum amount of formulas.

Written in a clear pedagogic style, this book deals with the application of density matrix theory to atomic and molecular physics. The aim is to precisely characterize sates by a vector and to construct general formulas and proofs of general theorems. The basic concepts and quantum mechanical fundamentals (reduced density matrices, entanglement, quantum correlations) are discussed in a comprehensive way. The discussion leads up to applications like coherence and orientation effects in atoms and molecules, decoherence and relaxation processes.

This third edition has been updated and extended throughout and contains a completely new chapter exploring nonseparability and entanglement in two-particle spin-1/2 systems. The text discusses recent studies in atomic and molecular reactions. A new chapter explores nonseparability and entanglement in two-particle spin-1/2 systems.

Basic Concepts.- General Density Matrix Theory.- Coupled Systems.- Irreducible Components of the Density Matrix.- Radiation from Polarized Atoms: Quantum Beats.- Some Applications.- The Role of Orientation and Alignment in Molecular Processes.- Quantum Theory of Relaxation.

From the reviews of the third edition:

"This book under review is of introductory nature being very useful and forming an effective foundation on the powerful density matrix formalism that was originally introduced by von Neumann to describe certain statistical concepts in the then (1927) fashionable quantum mechanics. ... The author´s worthy efforts in bringing out the latest edition are quite commendable, as the work would definitely help much in the study and research in the atomic and molecular processes as well as interactions."
