【摘要】:對(duì)稱性自發(fā)破缺和費(fèi)米液體理論作為凝聚態(tài)物理的兩大基石是我們理解凝聚態(tài)物質(zhì)的結(jié)構(gòu)、物性、相變的出發(fā)點(diǎn).在強(qiáng)關(guān)聯(lián)電子系統(tǒng)中,電子關(guān)聯(lián)效應(yīng)有可能導(dǎo)致超越對(duì)稱性自發(fā)破缺的新的有序形式和與之相應(yīng)的新的元激發(fā)形式.這些新的有序形式往往與量子力學(xué)特有的非局域性相關(guān),并伴隨著低能規(guī)范自由度的涌現(xiàn).為此,有必要擴(kuò)展傳統(tǒng)的朗道理論范式,使我們對(duì)物質(zhì)結(jié)構(gòu)的認(rèn)識(shí)提升到量子波函數(shù)的層次.
[Abstract]:Spontaneous symmetry breaking and Fermi liquid theory as the two cornerstones of condensed state physics is our understanding of condensed state structure, physical properties, the starting point of transformation. In strongly correlated electron system, electron correlation effect may lead to beyond the spontaneous symmetry breaking of new organized forms and the corresponding new the elementary excitation form. These new order forms are often associated with non local quantum mechanics characteristic, and is accompanied by the emergence of low-energy gauge degrees of freedom. Therefore, it is necessary to extend the traditional paradigm of Landau theory, to our understanding of the material structure up to the quantum wave function level.
