Bose-Einstein condensation of dilute gases is an exciting field of interdisciplinary physics. The eight chapters in this volume introduce its theoretical and experimental foundations. The authors are lucid expositors who have also made contributions to the field. They include theorists Tony Leggett, Allan Griffin and Keith Burnett, and Nobel Prize-winning experimentalist Bill Phillips. In addition to the introductory material, there are articles treating topics at the forefront of research, such as experimental quantum phase engineering of condensates, the "superchemistry" of interacting...
