It is a truely collection of insightful ideas. What is the BEC in real strognly correlated system? Most of books in this field just tell us the name of "order parameter" and "off-diagonal long-range order" but no further explanation and cites Penrose and Onsager's 1956 paper. That's all. But, here, this book explains THE IDEA what the physicist want. What is BEC, why does it occur, and how can we define it in general system?

As the title of book shows, Leggett explains superfluid and superconductor in the integrated point of view. Like the BEC chapter, he doesn't avoid the key ideas even if they are quite complicated in other's book. Moreover, Leggett give us very sharp and critical arguments about many things which are usually treated as typical or trivial in other's famous book.

One of the advantage of this book is difficulty. Most of readable books in this field are too out-of-date and old. Modern books are usually based on field theoretic formula and have tons of diagrams. But this book balances phenomenological, microscopic explanation, more over, experimental data and published in 2006. (It contains some arguments about rescent discovery such as supersolid and BEC-BCS crossover.)

In addition, the author is Nobel prize winner in 2003 about his ground-breaking papers about 3He. Hence this book not just a good book but also authoritive book. Highly recommended.
