附原文:5.0 out of 5 stars Green's functions, superfluids, superconductors, magnetism, December 11, 2004 By Jill Malter (jillmalter@aol.com) - See all my reviews (TOP 500 REVIEWER) This review is from: Statistical Physics, Part 2: Volume 9 (Course of Theoretical Physics Vol. 9) (Paperback) This review is for Volume 9 of the Landau Course of Theoretical Physics. The whole Course is clear and concise, so it makes sense for anyone who wants to do theoretical physics to go through all ten volumes. We start off with normal Fermi liquids and gases, including a nice discussion of Zero Sound (which is distinguished from normal sound mostly by a slight increase in the sound velocity as one gets colder than a transition temperature, and by increased absorption of sound near the transition temperature). Then we learn about Green's functions in a Fermi system at T = 0 and Feynman diagram representations of them. After that, we study Bose liquids and gases. That means the properties of superfluids, including quasi-particles (phonons and rotons) and quantized vortex filaments. And the book shows how to apply Green's functions to Bose liquids. There's an interesting section on the disintegration of quasi-particles. Next, we're introduced to Green's functions for T > 0, using the Matsubara operators to reduce the complexity of the diagrams. And then we're ready to learn about superconductors. That means learning about Cooper pairing and superfluid Fermi gases, and learning how to apply Green's functions to them. And, not surprisingly, we learn the Ginzburg-Landau equations, so that we can determine the behavior of superconductors in magnetic fields in temperature ranges near the transition point. There's also a chapter on electrons in the crystal lattice, including the de Hass-van Alphen effect (which refers to a metal's magnetic susceptibility oscillating as the strength of a strong magnetic field changes - due to the quantization of the energy levels of the electrons) and electron-phonon interactions. And there's a nice chapter on magnetism. In the preface, the authors state "we must again stress that this book is part of a course of theoretical physics and in no way attempts to be a textbook of solid state theory." Are they kidding? This course is an excellent way to learn solid state physics.
