量子相變

內(nèi)容概要

這是第一本系統(tǒng)介紹量子相變理論的專著,其中部分內(nèi)容也可作研究生教材。本書(shū)內(nèi)容新穎,涉及凝聚態(tài)物理學(xué)中廣泛關(guān)注的許多重要問(wèn)題。本書(shū)敘述簡(jiǎn)明，將理論模型的闡述與最新實(shí)驗(yàn)結(jié)果的介紹密切結(jié)合。書(shū)中著重描寫(xiě)和闡述存在量子相變的一些最簡(jiǎn)單的相互作用系統(tǒng)的物理性質(zhì)。全書(shū)大部分均忽略了無(wú)序效應(yīng)，而把注意力集中在這樣一些系統(tǒng)在非零溫度下的動(dòng)力學(xué)性質(zhì)，深入討論了以非彈性碰撞為主的量子動(dòng)力學(xué)及輸運(yùn)過(guò)程。
