高等統(tǒng)計(jì)物理

前言

　　統(tǒng)計(jì)物理架起人們由宏觀(guān)世界研究微觀(guān)世界的橋梁。凡出現(xiàn)B0ltzmann常數(shù)的理論就涉及統(tǒng)計(jì)物理。它是假設(shè)最少，結(jié)論眾多的一門(mén)學(xué)科。至今還沒(méi)有任何證據(jù)，確認(rèn)某些錯(cuò)誤必須由統(tǒng)計(jì)物理本身負(fù)責(zé)。這反映出該學(xué)科自然的關(guān)?！　∷殉蔀楝F(xiàn)代理論物理的一個(gè)重要部分。同時(shí)它又滲透到物理學(xué)的眾多領(lǐng)域，因此自然成為物理系的多個(gè)專(zhuān)業(yè)的研究生基礎(chǔ)課程。　　統(tǒng)計(jì)物理是研究體系的熱運(yùn)動(dòng)規(guī)律的學(xué)科。它有自己的特殊規(guī)律，不能從力學(xué)推導(dǎo)出來(lái)。但必須以力學(xué)為其基礎(chǔ)之一?；诮?jīng)典力學(xué)的，稱(chēng)經(jīng)典統(tǒng)計(jì)，基于量子力學(xué)的，稱(chēng)量子統(tǒng)計(jì)。通常大學(xué)生基礎(chǔ)課程中的統(tǒng)計(jì)物理以研究經(jīng)典統(tǒng)計(jì)為主，而研究生的高等統(tǒng)計(jì)，則以量子統(tǒng)計(jì)為主。　　本書(shū)的第一章是統(tǒng)計(jì)物理基本原理。第二章作為這些基本原理的簡(jiǎn)單應(yīng)用，解決幾個(gè)典型的統(tǒng)計(jì)物理問(wèn)題：量子理想氣體。第三章和第四章分別致力于多粒子體系和場(chǎng)的二次量子化。第五章研究玻色一愛(ài)因斯坦凝結(jié)。第六章研究一批量子統(tǒng)計(jì)中的反問(wèn)題，它們的陳氏（或Mobius-Chen）嚴(yán)格解公式，戴氏嚴(yán)格解公式及其漸近行為控制理論和反演理論的具體實(shí)現(xiàn)，特別是由高溫超導(dǎo)體的實(shí)際比熱數(shù)據(jù)，直接反演出聲子譜。第七章是Fermi和B0se的二次型哈密頓量的統(tǒng)一的對(duì)角化定理。

內(nèi)容概要

　　Statistical physics establishes a bridge from the macroscopic world to study the microscopic world. This is a theory with the fewest assumptions and the broadest conclusions. Up to now there is no evidence to show that statistical physics itself is responsible for any mistakes. Statistical physics has become an important branch of modern theoretical physics and this course has become one of the common fundamental courses of graduate students in different majors in physics departments.Statistical physics is a branch of science engaged in studying the laws of thermal motion of macroscopic systems. The advanced statistics for graduate students mainly studies quantum statistics. The first four chapters of this book are fundamental， and should be well known. The last five chapters are recent developments， including the studies on Bose-Einstein condensation， a class of inverse problems in quantum statistics （their Chens exact solution formulas， Dais exact solution formulas，asymptotic behavior control theory， and concrete realizations of the inversion theories）， an introduction to the theory of Greens functions in quantum statistics， the unified diagonalization theorem for Hamiltonians of quadratic form， and an introduction to the third formulation of quantum statistics and the functional integral approach. This course was edited by revising the lecture notes of the author， from courses of quantum statistics and advanced statistics for graduate students，since 1978. At the same time， this work contains the research results of some related projects， supported by the National Natural Science Foundation of China.
