Zusatztext This insightful book provides an expert guide to the application of phase-space methods in the burgeoning field of quantum atom optics. Building on their years of research experience in the field, the highly-respected authors provide a resource that will prove invaluable to graduate students and experienced researchers alike. The defining feature of this book is the comprehensive theoretical description of phase-space methods for both bosonic and fermionic systems. End-of-chapter exercises and the numerous appendices will make this an invaluable companion to graduate students embarking on a career in this field. Informationen zum Autor Bryan Dalton obtained a PhD degree in 1966 from Monash University. Following postdoctoral positions at University of Chicago and Australian National University, he joined the Department of Physics, University of Queensland in 1970, retiring as a Reader in 2000. His research was in theoretical quantum optics on topics such as non-classical states of light, coherent population trapping, laser-induced continuum structures, quantum beats, squeezed light spectroscopy and macroscopic cavity quantum electrodynamics. After 2000, he held research fellow positions at University of Sussex and Swinburne University of Technology, where he is currently an Adjunct Professor. He recently spent six months at University College, Cork as an ETS Walton Visiting Fellow. His more recent research interests have included decoherence effects in quantum computers, phase space theory in quantum and atom optics for Bose-Einstein condensates and Fermi gases, and entanglement theory for identical particle systems.John Jeffers is a Reader in the Physics Department at the University of Strathclyde and has been a researcher in quantum optics for twenty years. He obtained his PhD in Theoretical Physics from the University of Essex in 1993. Since then his research interests have included quantum dielectrics, quantum imaging, retrodictive quantum theory, quantum communication, quantum optical amplification and degenerate quantum gases.Stephen Barnett has been Professor of Quantum Optics since 1995, first at the University of Strathclyde and more recently at the University of Glasgow. He is best known for his discovery, with David Pegg, of the quantum phase operator, but he has wide-spread interests in quantum optics, quantum information, optics and, of course, cold-atom physics. His work has been recognised by the Royal Society, the Royal Society of Edinburgh and the Optical Society of America, all of which have elected him a Fellow. He was awarded the 2013 Dirac Medal and Prize for theoretical physics by the Institute of Physics. Klappentext This book aims to provide a theoretical framework for understanding the physics of degenerate quantum gases. It contains detailed derivations of all the key results and includes chapters covering necessary background mathematics, with many exercises being provided for readers who wish to check their understanding. Zusammenfassung Recent experimental progress has enabled cold atomic gases to be studied at nano-kelvin temperatures, creating new states of matter where quantum degeneracy occurs - Bose-Einstein condensates and degenerate Fermi gases. Such quantum states are of macroscopic dimensions. This book presents the phase space theory approach for treating the physics of degenerate quantum gases, an approach already widely used in quantum optics. However, degenerate quantum gases involve massive bosonic and fermionic atoms, not massless photons. The book begins with a review of Fock states for systems of identical atoms, where large numbers of atoms occupy the various single particle states or modes. First, separate modes are considered, and here the quantum density operator is represented by a phase space distribution function of phase space variables which replace mode annihilation, creation operators, the dynamical equation for the...
