本書1999年初版,2003、2008年重印,旨在將固態(tài)物理學(xué)的標(biāo)準入門教材和講述其發(fā)展的專著之間架起一座橋梁。從最基本的磁性理論問題開始,到相對基礎(chǔ)的專題,如重費米子,Mott過渡,量子磁性。盡管這部教材相對比較理論,但并沒有假定讀者具備一定的理論知識,也討論一些實驗發(fā)現(xiàn)。自始至終有問題相伴,并給出了詳細解答。
目次:導(dǎo)論;原子、離子和分子;晶體場論;Mott過渡和Hubbard模型;Mott絕緣體;Heisenberg磁體;巡游電子磁性;Hubbard模型中的鐵磁性;Gutzwiller變分法;關(guān)聯(lián)金屬態(tài);混合價和重費米子;量子霍爾效應(yīng)。
讀者對象:物理、理論物理專業(yè)的研究生和科研人員。
