Theory of spin glasses
WebbThis book aims to describe in simple terms the new area of statistical mechanics known as spin-glasses, encompassing systems in which quenched disorder is the dominant factor. The book begins with a non-mathematical explanation of the problem, and the modern understanding of the physics of the spin-glass state is formulated in general terms. Webbbehaves like a small magnet, or spin, which is affected by the other magnets around it. However, in a spin glass they are frustrated and have difficulty choosing which direction …

Present work is a first application of this tool to determine critical temperatures for the phase transitions in Edwards–Anderson systems.
WebbAbstract: An analysis of disorder is given, based on the concept of local invariance. The frustration effect is defined and several fundamental concepts are introduced. Spin … WebbThe first part covers the physics of spin-glass states using results obtained within the framework of the mean field theory of spin glasses. The second part is devoted to the theory of critical phenomena in the presence of weak quenched disorder. This includes a systematic derivation of the traditional renormalization group theory.
