本書主要講解量子力學(xué)基本原理在現(xiàn)代原子物理學(xué)中的應(yīng)用。在新版中,作者增添了理論原子物理領(lǐng)域的最新進(jìn)展,介紹了目前大家非常感興趣的議題,包括半經(jīng)典周期軌道理論、外場(chǎng)中原子的標(biāo)度性質(zhì)、雙電子原子的經(jīng)典和量子動(dòng)力學(xué)以及原子氣體的玻色-愛(ài)因斯坦凝聚等。本書還簡(jiǎn)明介紹了原子光學(xué)中若干前沿研究,這是目前和未來(lái)超冷原子實(shí)驗(yàn)必不可少的知識(shí)。作者強(qiáng)調(diào)基本理論的解釋,使讀者能夠理解標(biāo)準(zhǔn)理論結(jié)構(gòu)里蘊(yùn)藏的豐富物理思想,從而可以獨(dú)立進(jìn)行科學(xué)研究工作。此外,形式各異的習(xí)題及其完整的解答過(guò)程為本書添色不少。本書被選為德國(guó)Springer出版社的“高等物理學(xué)教材”,這是一套非常優(yōu)秀的教材。目次:量子力學(xué)概要;原子和離子;原子光譜;簡(jiǎn)單反應(yīng);專題;附錄:特殊數(shù)學(xué)函數(shù);習(xí)題答案;索引。
原子物理是物理學(xué)中最具有活力的前沿領(lǐng)域之一,它在推動(dòng)人們對(duì)自然界的認(rèn)知方面發(fā)揮了重要作用。在過(guò)去幾年里,該領(lǐng)域及相關(guān)領(lǐng)域因原子激光冷卻(1997年)、玻色-愛(ài)因斯坦凝聚的實(shí)現(xiàn)(2001年)以及光的量子相干性與精密光譜學(xué)的發(fā)展(2005年)三次摘取諾貝爾物理學(xué)獎(jiǎng)桂冠。讀者對(duì)象:理論物理、原子分子物理和物理化學(xué)等專業(yè)的高年級(jí)本科生、研究生和相關(guān)領(lǐng)域的科研人員。
