Coherent dynamics of complex quantum systems A large number of modern problems in physics chemistry and quantum electronics require a consideration of population dynamics in complex multilevel quantum systems. The purpose of this book is to provide a systematic treatment of these questions and to present a number of exactly solvable problems. It considers the different dynamical problems frequently encountered in different areas of physics from the same perspective based mainly on the fundamental ideas of group theory and on the idea of ensemble average. Also treated are concepts of complete quantum control and correction of decoherence induced errors that are complementary to the idea of ensemble average. Coherent Dynamics of Complex Quantum Systems is aimed at senior level undergraduate students in the areas of Atomic Molecular and Laser Physics Physical Chemistry Quantum Optics and Quantum Informatics. It should help them put particular problems in these fields into a broader scientific context and thereby take advantage of the well elaborated technique of the adjacent fields.
