作者簡介

作者：(美國)艾里斯 (Richard S.Ellis)艾里斯，Richard S.Ellis，received his B.A. degree in mathematics and German literature from Harvard University in 1969 and his Ph.D. degree in mathematics from New York University in 1972. After spending three years at Northwestern University, he moved to the University of Massachusetts, Amherst, where he is a Professor in the Department of Mathematics and Statistics and Adjunct Professor in the Depart-ment of Judaic and Near Eastern Studies. His research interests in mathematics focus on the theory of large deviations and on applica-tions to statistical mechanics and other areas.

章節(jié)摘錄

版權(quán)頁：插圖：In the next three chapters we apply the theory of large deviations to analyze some basic models in equilibrium statistical mechanics.' This branch of physics applies probability theory to study equilibrium properties of systems consisting of a large number of particles. The systems fall into two groups:continuous systems, which include the solids, liquids, and gases common to everyday experience; and lattice systems, of which ferromagnets are the main example. This chapter introduces the continuous theory by treating a simple model called a discrete ideal gas. This model, which has no interactions, is a physical analog of i.i.d, random variables.The macroscopic description of a physical system such as an ideal gas isgiven by thermodynamics. Thermodynamics summarizes the properties ofthe gas in terms of macroscopic variables such as pressure, volume, tempera- ture, and internal energy. But this theory takes no account of the fact that the gas is composed ofrnolecules. The main aim of statistical mechanics is to derive properties of the gas from a probability distribution which describes its microscopic （i.e., molecular） behavior. This distribution is called an ensemble.
