Theoretical Atomic Physics

This expanded and updated well-established textbook contains an advanced presentation

of quantum mechanics adapted to the requirements of modern atomic physics. It

includes topics of current interest such as semiclassical theory, chaos, atom optics and

Bose-Einstein condensation in atomic gases. In order to facilitate the consolidation

of the material covered, various problems are included, together with complete

solutions. The emphasis on theory enables the reader to appreciate the fundamental

assumptions underlying standard theoretical constructs and to embark on independent

research projects.

The fourth edition of Theoretical Atomic Physics contains an

updated treatment of the sections involving scattering theory and near-threshold

phenomena manifest in the behaviour of cold atoms (and molecules). Special attention

is given to the quantization of weakly bound states just below the continuum threshold

and to low-energy scattering and quantum reflection just above. Particular emphasis

is laid on the fundamental differences between long-ranged Coulombic potentials

and shorter-ranged potentials falling off faster than 1/r2 at large distances r. The new

sections on tunable near-threshold Feshbach resonances and on scattering in two spatial

dimensions also address problems relevant for current and future research in the field

of cold (and ultra-cold) atoms. Graduate students and researchers will find this book a

valuable resource and comprehensive reference alike.
