    Abstract: 本計畫將繼續研究下列兩課題: (1)Frenkel-Kontorava模型:Frenkel-Kontoraa(FK)模型為探 討相稱一不相稱相變(Commensurate-Incommensurete phase transition)之簡單一維模型.它包含一系列處 在一週期性外場(如正弦型場)中,並彼此以某種 相互作用力互相影響的原子鏈.此兩作用力相 競爭的結果,可在一定條件下形成穩定之不相 稱結構.我們正在研究原子作用力為雙曲余弦 型(Cosh)之廣義FK模型的性質,具相變點及相關之 臨界指數的變化情形;(2) Wilson-Line對稱破壞機 制:我們正在研究有限溫度及密度在環面上對 Wilson Line機制的影響.我們將著重在以溫度、密 度以及環而大小比例為控制參數之相變相圖( Phase diaqreuns)之探討,並研究在不同規範群(GougeGroups)之臨界參數的普適性(Universality).
