Most of the matter in our universe is in a gaseous or plasma state. Yet,
most textbooks on quantum statistics focus on examples from and
applications in condensed matter systems, due to the prevalence of
solids and liquids in our day-to-day lives. In an attempt to remedy that
oversight, this book consciously focuses on teaching the subject matter
in the context of (dilute) gases and plasmas, while aiming primarily at
graduate students and young researchers in the field of quantum gases
and plasmas for some of the more advanced topics. The majority of the
material is based on a two-semester course held jointly by the authors
over many years, and has benefited from extensive feedback provided by
countless students and co-workers. The book also includes many
historical remarks on the roots of quantum statistics: firstly because
students appreciate and are strongly motivated by looking back at the
history of a given field of research, and secondly because the spirit
permeating this book has been deeply influenced by meetings and
discussions with several pioneers of quantum statistics over the past
few decades.
