ABSTRACT
Nonideal Bose …uids, such as liquid helium-4, and Fermi …uids, such as liquid helium-3, require quantum statistics for a description of their properties. Powerful approaches such as Fermi liquid theory have been developed for treating quantum …uids, but a detailed discussion of these topics is beyond the scope of this book. e discussion of quantum …uids is therefore fairly brief and classical systems are considered ˆrst.
