I found this is a very good reference for my beginning in studying of lattice dynamics and thermodynamics of crystals. It provides the theory framework for the equilibrium thermodynamics properties of perfect crystals. To me, this book is very helpful to understand the theory in physics of solid state. It starts with the basic theories of thermodynamics, such as, thermodynamics functions, state variables, wave propagation, etc.. Then it moves to crystal potentials (and their expansions about the equilibrium configuration, the stability and symmetries. etc), to crystal vibration problems(eigenvalue problems and operator theories for Hamiltonian system), and to the advance topic of phonon thermodynamics, band-structure theory, and pseudopotential perturbation theory. Finally, it provides the model calculation and experimental data analysis. All materials are treated gradually from simple to complicated (I means mathematically) Graduate level knowledge in mathematics is necessary to read this book. Allover, I think this is a very good reference. "
this is the best reference book i have found on this topic. everything you could reasonably expect is spelled out in it explicitly. highly recommended. "
