The aim of this series is to provide a broad range of high quality books, suitable for experimentalists and theorists, covering all aspects of atomic, molecular and chemical physics. It seeks on the one hand to present authoritative reviews of mature areas of the subject and on the other to provide accounts of rapidly developing new directions of research that have the potential to be major advances. The books are intended to play a unifying role, bringing together experimental, theoretical and applied research in atomic, molecular and chemical physics at a level accessible to graduate students and interesting to senior researchers.
