本书1999年初版,2003、2008年重印,旨在将固态物理学的标准入门教材和讲述其发展的专著之间架起一座桥梁。从最基本的磁性理论问题开始,到相对基础的专题,如重费米子,Mott过渡,量子磁性。尽管这部教材相对比较理论,但并没有假定读者具备一定的理论知识,也讨论一些实验发现。自始至终有问题相伴,并给出了详细解答。
目次:导论;原子、离子和分子;晶体场论;Mott过渡和Hubbard模型;Mott绝缘体;Heisenberg磁体;巡游电子磁性;Hubbard模型中的铁磁性;Gutzwiller变分法;关联金属态;混合价和重费米子;量子霍尔效应。
读者对象:物理、理论物理专业的研究生和科研人员。
