Now updated-the leading single-volume introduction to solid state and soft condensed matter physics
This Second Edition of the unified treatment of condensed matter physics keeps the best of the first, providing a basic foundation in the subject while addressing many recent discoveries. Comprehensive and authoritative, it consolidates the critical advances of the past fifty years, bringing together an exciting collection of new and classic topics, dozens of new figures, and new experimental data.
This updated edition offers a thorough treatment of such basic topics as band theory, transport theory, and semiconductor physics, as well as more modern areas such as quasicrystals, dynamics of phase separation, granular materials, quantum dots, Berry phases, the quantum Hall effect, and Luttinger liquids. In addition to careful study of electron dynamics, electronics, and superconductivity, there is much material drawn from soft matter physics, including liquid crystals, polymers, and fluid dynamics.
Provides frequent comparison of theory and experiment, both when they agree and when problems are still q unsolved Incorporates many new images from experiments q Provides end-of-chapter problems including computational exercises q Includes more than fifty data tables and a detailed forty-page index q Offers a solutions manual for instructors q Featuring 370 figures and more than 1,000 recent and historically significant references, this volume serves as a valuable resource for graduate and undergraduate students in physics, physics professionals, engineers, applied mathematicians, materials scientists, and researchers in other fields who want to learn about the quantum and atomic underpinnings of materials science from a modern point of view.

Editorial Review
Review "In summary, the main strength of the book is that it conveys the enormous breadth of modern condensed matter physics and gives a basic, often conceptual account of these diverse topics." (Physics Today, June 2001) "...there is clearly much here that lecturers and readers at the graduate level will find valuable." (Contemporary Physics, Vol 41/5, 2000) "I can thoroughly recommend it to students, graduates and teachers. I would even say that everyone who is interested more deeply in the exciting world of matter should have this book on their library shelf." (European Journal of Physics, Vol 21, 2000) "...responds to the need in both the academic and research communities for a modern introductory treatment of this essential subject." (Zeitschrift Fur Kristollographie, Vol. 218, No. 7, 2003) From the Back Cover A modern, unified treatment of condensed matter physics This new work presents for the first time in decades a sweeping review of the whole field of condensed matter physics. It consolidates new and classic topics from disparate sources, teaching "not only about the effective masses of electrons in semiconductor crystals and band theory, but also about quasicrystals, dynamics of phase separation, why rubber is more floppy than steel, electron interference in nanometer-sized channels, and the quantum Hall effect." Six major subjects are covered-atomic structure, electronic structure, mechanical properties, electron transport, optical properties, and magnetism. But rather than defining the field in terms of particular materials, the author focuses on the way condensed matter physicists approach physical problems, combining phenomenology and microscopic arguments with information from experiments. For graduate students and professionals, researchers and engineers, applied mathematicians and materials scientists, Condensed Matter Physics provides: * An exciting collection of new topics from the past two decades * A thorough treatment of classic topics, including band theory, transport theory, and semiconductor physics * Over 300 figures, incorporating many images from experiments * Frequent comparison of theory and experiment, both when they agree and when problems are still unsolved * More than 50 data tables and a detailed index * Ample end-of-chapter problems, including computational exercises * Over 1,000 references, both recent and historically significant About the Author MICHAEL P. MARDER, PhD, is Associate Professor of Physics at the University of Texas at Austin and a member of the internationally known Center for Nonlinear Dynamics.

Thelma Scott:
This Condensed Matter Physics book is simply not ordinary book, you have after that it the world is in your hands. The benefit you receive by reading this book is usually information inside this e-book incredible fresh, you will get facts which is getting deeper anyone read a lot of information you will get. This particular Condensed Matter Physics without we comprehend teach the one who reading it become critical in contemplating and analyzing. Don't become worry Condensed Matter Physics can bring any time you are and not make your carrier space or bookshelves' grow to be full because you can have it inside your lovely laptop even cell phone. This Condensed Matter Physics having fine arrangement in word and also layout, so you will not experience uninterested in reading.

Geraldine Louis:
A lot of people always spent their particular free time to vacation as well as go to the outside with them loved ones or their friend. Do you know? Many a lot of people spent they free time just watching TV, or even playing video games all day long. In order to try to find a new activity this is look different you can read some sort of book. It is really fun to suit your needs. If you enjoy the book you read you can spent the whole day to reading a e-book. The book Condensed Matter Physics it is rather good to read. There are a lot of people that recommended this book. We were holding enjoying reading this book. In the event you did not have enough space to bring this book you can buy often the e-book. You can m0ore very easily to read this book through your smart phone. The price is not too costly but this book provides high quality.

Keith Mayo:
The book untitled Condensed Matter Physics contain a lot of information on the item. The writer explains your ex idea with easy method. The language is very simple to implement all the people, so do not necessarily worry, you can easy to read that. The book was authored by famous author. The author gives you in the new period of literary works. It is possible to read this book because you can continue reading your smart phone, or gadget, so you can read the book throughout anywhere and anytime. If you want to buy the e-book, you can open their official web-site and also order it. Have a nice go through.

Maria Simmons:
What is your hobby? Have you heard this question when you got scholars? We believe that that question was given by teacher on their students. Many kinds of hobby, Everyone has different hobby. And you know that little person similar to reading or as reading become their hobby. You must know that reading is very important along with book as to be the issue. Book is important thing to provide you knowledge, except your teacher or lecturer. You see good news or update in relation to something by book. A substantial number of sorts of books that can you choose to use be your object. One of them is Condensed Matter Physics.
