一种一维非对角Fibonacci准晶模型的延展态

EXTENDED STATE IN A ONE-DIMENSIONAL OFF-DIAGONAl-FIBONACCI QUASICRYSTAL MODEL

研究一个实际上更有可能存在的Fibonacci序列SSLSSSSLS．上的一维非对角准品模型用KKT方法计算了其能谱、E＝0的本征函数及其多分形谱f（a）～a．结果表明，这个本征态是一个延展态．这个结果与通常的Fibonacci序列ABAAB……上的完全不同。

A one - dimensional off -- diagonal Fibonacci quasicrystal model on the sequence SSLSSSSLS... is represented. The energy spectrum, the eigen function at E = 0 and its multifractal spectrum is calculated by KKT method. The results show that the eigen state is extended which is in striking contrast to tile well -- studied off - diagonal Fibonacci model on the seuence ABAAB...
