Book Description

The electron density of a nondegenerate ground state system determines essentially all physical properties of the system. This statement of the Hohenberg--Kohn theorem of Density Functional Theory plays an exceptionally important role among all the fundamental relations of molecular physics. Electron densities provide detailed information that gives important insight into the fundamentals of molecular structure and a better understanding of chemical reactions. If the functional form of a molecular electron density is known, then various molecular properties affecting reactivity can be determined by quantum chemical computational techniques or alternative approximate methods.This book contains a selection of chapters based on papers given at the 12th conference of the Commission of Charge, Spin and Momentum Density of the International Union for Crystallography, held in Waskiesiu, Prince Albert National Park, Canada, on July 27 -- August 1, 1997. The choice of topics represents some of the latest advances in the field of electron, spin, and momentum densities and the analysis of these densities with respect to their roles in determining chemical reactivity. This book provides an exciting collection of accounts of the latest advances, and also provides further motivation for new research to address some of the challenging, unsolved problems of the fascinating interrelations between electron, spin, and momentum densities, and the complex subject of chemical reactivity. ...

Book Description

This revised and expanded edition of one of the important textbook in statistical physics, is a graduate level text suitable for students in physics, chemistry, and materials science.

After a short review of basic concepts, the authors begin the discussion on strongly interacting condensed matter systems with a thorough treatment of mean field and Landau theories of phase transitions. Many examples are worked out in considerable detail. Classical liquids are treated next. Along with traditional approaches to the subject such as the virial expansion and integral equations, newer theories such as perturbation theory and density functional theories are introduced.

The modern theory of phase transitions occupies a central place in this book. The development is along historical lines, beginning with the Onsager solution of the two-dimensional Ising model, series expansions, scaling theory, finite-size scaling, and the universality hypothesis. A separate chapter is devoted to the renormalization group approach to critical phenomena. The development of the basic tools is completed in a new chapter on computer simulations in which both Monte Carlo and molecular dynamics techniques are introduced.

The remainder of the book is concerned with a discussion of some of the more important modern problems in condensed matter theory. A chapter on quantum fluids deals with Bose condensation, superfluidity, and the BCS and Landau-Ginzburg theories of superconductivity. A new chapter on polymers and membranes contains a discussion of the Gaussian and Flory models of dilute polymer mixtures, the connection of polymer theory to critical phenomena, a discussion of dense polymer mixtures and an introduction to the physical properties of solid and fluid membranes. A chapter on linear response includes the Kubo formalism, the fluctuation-dissipation theorem, Onsager relations and the Boltzmann equation. The last chapter is devoted to disordered materials.

Each chapter contains a substantial number of exercises. A manual with a complete set of solutions to these problems is available under separate cover. ... Read more

A fine advanced book on statistical physics
I liked this book a lot since the first time I read the first edition. It's extremely up to date, many of the examples come from cutting edge research (like the very fashionable soft condensed matter field). Butbeware the level is a bit high, so it's probably not a good choice to learnabout this subject on your own. Its highest utility is as a help toteachers and as a companion of a course on statistical mechanics.

A good survey of condensed matter
The focus of this book is squarely on condensed matter physics and so it is definitely not a recommended resource for learning the foundations of statistial mechanics. As such, if you are new to any of the material, this book on its own will not be of much use. It is certainly not "self-contained", as stated on the back cover, as important topics, such as the various models of ferromagnetism, are not fully described or developed before approximation techniques are introduced. That said, this book contains a wealth of information that would be difficult to find in any other single volume. The authors discuss a range of topics from ferromagnetism to quantum fluids, and there is even a good chapter on computer simulations. As many of the systems encountered in condensed matter are not exactly solvable, the emphasis is necessarily on approximation techniques though there is some discussion of the few exact solutions available (for example, there is a detailed derivation of the exact solution to the 2-d Ising Model on the square lattice). An extensive bibliography contains many good references, often to the original papers. All in all, this book is recommended to anyone with a firm grounding in statistical mechanics (and quantum mechanics) who is looking to study condensed matter physics. Keep in mind that this book was published in 1994 so it may not be as current as some. A 3rd edition would be most welcome. ... Read more

Book Description

This book is a tribute to the life and work of J Q Chen. The contributions of Chen to nuclear and molecular physics are discussed vis-à-vis present developments in these fields. Among other subjects, the present status of microscopic theories of the interacting boson model in nuclear physics and the theory of symmetry adaptation of molecular vibrations in molecular physics are reviewed. The latter theory is particularly useful for large molecular species such as fullerenes, where icosahedral symmetry plays a fundamental role. ... Read more

Forces you know or not????
The above "reviewer" needs to learn the English language! What the hell is that guy trying to tell us? I'm glad the book is useful to the outdoors.

I have not read too far into the book, but it seems to be fairly well written.

Forces you know or not
~~~Engineering and Science are different on the point that people are trying to understand the phenomena with little knowledge of the physical background. Especially recently the interdisciplinary stuff are more and more challenging, so that's why engineers must have solid background on science. From my own experience, I do not need to take care the thermodyamics, kinetics in my former major, solid mechanics. Well, it's hard to survive if you only have knowledge on structures of a bridge~~ or a composite plate (this is just my own view, please forgive my ignorance). Nano- and Meso- scale materials are related to some mechanical problems. So I got this book to start my research on this. It is useful not only to experts but also to the outdoors like me.~~~ ...

As before the species have been grouped according to chemical aspects. For each group of substances the literature has been compiled and extracted by experts in the fields. For the readers convenience an index of substances follows in the last subvolume. ... Read more

Book Description

In 2001, the Nobel Foundation celebrated the 100th anniversary of the first Nobel Prize, and all previous Nobel laureates were invited to attend the Nobel ceremonies in Stockholm. This gave an excellent opportunity for arranging jubilee symposia with topics that would attract several of the laureates. The chosen subject of "Condensation and Coherence in Condensed Systems" attracted sixteen Nobel laureates and another thirty-five leading scientists.

The idea was to bring scientists together from several related subdisciplines: atomic physics, quantum optics, and condensed matter physics, for cross-breeding of ideas, concepts, and experience. Subjects like phase transitions in strongly coupled systems, Bose–Einstein condensation in weakly coupled systems, macroscopic quantum phenomena, coherence in mesoscopic structures, and quantum information were intensively discussed from different points of view. Coherence phenomena in condensed systems were emphasized. A special session was devoted to the emerging field of quantum computing, with experimental and theoretical results reported for different types of qu-bits. The 2001 Nobel Prize awarded to Eric Cornell, Wolfgang Ketterle, and Carl Wieman, "for the achievement of Bose–Einstein condensation in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates," gave an extra flavor to the theme of the Centennial Symposium. ...

Book Description

Alkali-doped fullerides have attracted strong interest since their production became possible about fifteen years ago. This book presents recent work which may solve intriguing problems arising from a variety of remarkable properties. For example, these solids are superconductors with high transition temperatures, although the similarity between the electronic and phonon energy scales should suppress superconductivity. Moreover, the Ioffe–Regel condition for electrical conductivity is strongly violated. The book shows why superconductivity is nevertheless possible, owing to a local pairing mechanism. The Ioffe–Regel condition is derived quantum-mechanically, and it is explained why the underlying assumptions are violated for fullerides and high-Tc cuprates, for example. The book treats electronic and transport properties, reviewing theoretical and experimental results. It focuses on superconductivity, electrical conductivity and metal–insulator transitions, emphasizing the electron–electron and electron–phonon interactions as well as the Jahn–Teller effect. ...
