摘要/Abstract

摘要： 使用一个具有实际意义的双阱势作为原子间作用势、受扰余弦势势作为外势,引入一个新的FK类模型,用有效势方法研究其相图。发现了一系列新奇的、复杂的,但同时又有一定规律可循的相结构。

关键词: CI相变, FK模型, 有效势

Abstract: A generalized FK model is presented for treating phase transition problem with double-well interatomic interactions and a perturbed sinusoidal external potential,in which the interatomic interaction is of realistic significance.The effective potential method is used to study its phase diagram and a series of novel,complex but regular phase structures have been found.

Key words: CI transition, FK model, the effective potential
