Exactly solved models in statistical mechanics by Rodney J. Baxter PDF

By Rodney J. Baxter

This article explores the answer of two-dimensional lattice types. subject matters comprise easy statistical mechanics, Ising versions, the suggest box version, the round version, ice-type versions, nook move matrices, difficult hexagonal versions, and elliptic features. the writer has up to date the 1989 model with a brand new bankruptcy, "Subsequent Developments," for the 2007 variation.

Download PDF by Michael V. Sadovskll: Diagrammatics: lectures on selected problems in condensed

By Michael V. Sadovskll

The creation of quantum box idea tools has resulted in one of those “revolution” in condensed subject concept. This led to the elevated value of Feynman diagrams or diagram strategy. It has now develop into central for execs in condensed subject concept to have an intensive wisdom of this system. there are numerous strong books that conceal the final points of diagrammatic tools. while, there was a emerging want for books that describe calculations and methodical “know how” of particular difficulties for rookies in graduate and postgraduate classes. This special choice of lectures addresses this desire. the purpose of those lectures is to illustrate the applying of the diagram strategy to assorted difficulties of condensed topic concept. a few of these difficulties aren't “finally” solved. however the improvement of effects from any component to this booklet may perhaps function a kick off point for a major theoretical research.

Variational principles in dynamics and quantum theory by Wolfgang Yourgrau PDF

By Wolfgang Yourgrau

Targeting purposes proper to fashionable physics, this article for complex undergraduates and graduate scholars surveys variational rules, interpreting their courting to dynamics and quantum concept. It stresses the background and idea of those techniques instead of their mechanics, supplying many insights into the improvement of quantum mechanics. 1968 version.
