Describing the physical properties of quantum materials near critical points with long-range many-body quantum entanglement, this book introduces readers to the basic theory of quantum phases, their phase transitions and their observable properties. This second edition begins with a new section suitable for an introductory course on quantum phase transitions, assuming no prior knowledge of quantum field theory. It also contains several new chapters to cover important recent advances, such as the Fermi gas near unitarity, Dirac fermions, Fermi liquids and their phase transitions, quantum magnetism, and solvable models obtained from string theory. After introducing the basic theory, it moves on to a detailed description of the canonical quantum-critical phase diagram at non-zero temperatures. Finally, a variety of more complex models are explored. This book is ideal for graduate students and researchers in condensed matter physics and particle and string theory.

Updated second edition with several new chapters, for graduates and researchers in condensed matter physics and particle and string theory.

Reviews
Review of the first edition: 'Taken as a whole, this book is something of a theoretical masterpiece. With its tight organization, the book leads the determined (and theoretically inclined) reader on a tour encompassing some of the most challenging yet beautiful topics in contemporary theoretical physics ... Virtually every chapter contains a theoretical 'gem' ... The equations are manipulated with flair and elegance that are testimony to Sachdev's talent as one of the world's premier theorists.' Physics Today
'The book is well written from a pedagogical point of view and hence suitable for non-specialists. On the other hand, it can be used (some chapters) by graduate students as well.' Farruh Mukhamedov, Zentralblatt MATH
'... a timely and well-informed update to the subject and provides graduate and advanced students with enough material to understand and tackle these very interesting systems.' Contemporary Physics
