New enlarged edition including new chapters on entanglement, open quantum systems, control and coherence protection
Help taking advantage of well established techniques used in adjacent fields puting particular problems in modern quantum physics into a broader scientific context
Based on the author’s lectures at the Moscow Institute of Physics and Technology, at the CNRS Aime Cotton Laboratory, and on other courses he has held over the last two decades
This book gathers together a range of similar problems that can be encountered in different fields of modern quantum physics and that have common features with regard to multilevel quantum systems. The main motivation was to examine from a uniform standpoint various models and approaches that have been developed in atomic, molecular, condensed matter, chemical, laser and nuclear physics in various contexts. The book should help senior-level undergraduate, graduate students and researchers putting particular problems in these fields into a broader scientific context and thereby taking advantage of well-established techniques used in adjacent fields. This second edition has been expanded to include substantial new material (e.g. new sections on Dynamic Localization and on Euclidean Random Matrices and new chapters on Entanglement, Open Quantum Systems, and Coherence Protection). It is based on the author’s lectures at the Moscow Institute of Physics and Technology, at the CNRS Aimé Cotton Laboratory, and on other courses he has given over the last two decades.
