一维准晶的电子能级互吸引现象

LEVEL CLUSTERING IN THE ENERGY SPECTRA OF ONE-DIMENSIONAL QUASIPERIODIC LATTIES

研究一维准晶电子能谱与准周期调制强度的关系．对Ｆｉｂｏｎａｃｃｉ链和一类泛Ｆｉｂｏｎａｃｃｉ链的计算结果表明，一维准晶电子能级具有相互吸引成簇的特点，明显不同于周期系统的能级排斥现象．

This paper is devoted to the study of the electronic energy Spectrum of one-di mensional quasiperiodic lattices. Numerical results show that the energy spectrum of one dlimensional quasiperiodic lattices is characterized by the level clustering,Which is quite dif ferent from the level repulsion in periodic system.
