"...detailed and highly informative...The descriptions are... mathematical and well illutrated by figures and diagrams...I recommend it...the main audience for this book...is clearly the theoretical condensed matter physics community." R.J. Cava, Materials Research Bulletin
"...a concise introduction to the theory of local-moment physics. Hewson provides a thorough and reliable foundation for those interested in research in strongly correlated materials. I heartily recommend it." Piers Coleman, Physics Today
"...I strongly recommend this book to any reader interested in reading about the solution of the Kondo problem, or to graduate students who wish to prepare themselves for research into strongly correlated electron systems. I am sure that experts in the field will read the book and enjoy it. I came away wanting to read more!" Peter S. Riseborough, Foundations of Physics
The behaviour of magnetic impurities in metals has posed problems to challenge the condensed matter theorist over the past 30 years. This book deals with the concepts and techniques which have been developed to meet this challenge, and will be of interest to condensed matter physicists, particularly those interested in strong correlation problems.
