The volume focuses on mean-field and exact-solution methods for classical finite-spin systems. It starts with a useful summary of the motivating thermodynamic notions, and its material can be roughly classified in three categories: (1) one-dimensional models (Ising, lattice gas and relatives); (2) mean-field approximations and their many-site generalizations (cluster-variation methods); and (3) exact solutions for spin models in larger dimensions (Ising, models in decorated lattices, six-vertex models) based either on duality transformations or on transfer-matrix techniques. The book takes a physicist's viewpoint: experimental data, rather than mathematical control, is used to gauge the quality of approximation schemes. Finer mathematical points, for instance those associated with the infinite-volume limit, are only the subject of brief comments. The book manages to put together a wealth of information in a simple, accessible manner. While leaving aside some issues heavily studied in recent decades (e.g. correlation inequalities, systems with continuous spins, hierarchical models), the authors present a very rich variety of material, generous in applications (model for DNA denaturation, water-like models, mixture models, amphipathic monolayers, $\dots$), which allows them to introduce a broad taxonomy of critical and phase-transition phenomena (azeotropy, multicritical points, ferro-, para-, antiferro-, ferri-, meta-magnetism, etc.). The book is of immediate interest to practitioners and teachers in physical---as opposed to mathematical---statistical mechanics. It offers a self-contained survey both of the main notions of the field and of approximate methods that are usually the first (and often the only) resource to study complicated systems. It can also be a useful reference for more mathematically inclined people wishing to understand concepts and arguments of widespread use in physics and chemistry. ----------- Review from MathSciNet MR1683783 (2001g:82002) Lavis, David A.(4-LNDKC); Bell, George M.

As in the first volume [Statistical mechanics of lattice systems. Vol. 1, Second edition, Springer, Berlin, 1999; MR1683784 (2001g:82001); see the preceding review], the emphasis in most chapters is on the algebraic and algorithmic aspects of the methods, rather than on mathematical control (a conspicuous exception is Chapter 4, as I comment below). Existence and convergence issues are left aside or mentioned only briefly. All systems studied are classical and with finite spin, except for the application of cluster-expansion methods to the classical and quantum Heisenberg models. After a quick review of thermodynamical notions the book develops the following topics: (1) A rather complete presentation of scaling theory, at the heuristic level, including finite-size scaling and conformal invariance. (2) Landau and Landau-Ginzburg theories of critical behavior. (3) Rigorous methods, e.g., Peierls' contour argument, Lee-Yang theorems, transfer matrices and their relation with Perron-Frobenius theory, and a more recent method due to Wood and collaborators based also on the study of the loci of the complex zeroes of the partition function. In this chapter, unlike the rest of both volumes, the authors develop a rather rigorous mathematical theory, including theorems and proofs. (4) Exact solution of the 8-vertex model. (5) Real-space renormalization. This is an honest, informative and concise presentation of techniques based on the block-renormalization idea. In less than 50 pages, the general approach is clearly stated, most practical approximate implementations are reviewed and illustrated, and the limitations and potential problems of the usual approaches are spelled out (in particular Griffiths and Pearce's peculiarities [R. B. Griffiths and P. A. Pearce, J. Statist. Phys. 20 (1979), no. 5, 499--545; MR0533527 (81m:82005)], systematically studied later [A. C. D. van Enter, R. Fernandez and A. D. Sokal, J. Statist. Phys. 72 (1993), no. 5-6, 879--1167; MR1241537 (94m:82012)]). (6) Series expansions---low-temperature, high-temperature and more general cluster expansions---with applications to Ising, Potts and classical and quantum Heisenberg models. (7) Solutions for dimer systems, with applications to the exact solution of the two-dimensional Ising model (already studied in Volume 1) and to a model of amphipathic monolayers (different from the one presented in Volume 1). As the list shows, the authors offer in a single, largely self-contained volume a true catalogue of very important techniques. Together, both volumes cover almost all the main methods used in practice by theoretical physicists and chemists to study classical lattice models. They are useful on several grounds: for teaching purposes, as a learning resource for applied researchers, as a bibliographical source (especially for work published up to the mid-1980s), and as inspiration and reference for people studying mathematical and foundational issues.
