| 摘 要： | 本文应用叠代法分别求出了两种广义 Fibonacci 准周期伊辛链的配分函数。研究了它们的低温热力学性质,发现当温度超于零时,其热力学函数在某些参数值发生尖锐的变化。详细分析了零温时两种系统在不同参数范围内的基态构形,解释了系统出现奇异性的原因。

| Abstract: | The partition functions of two kinds of general Fibonacci quasiperiodic frustratedIsing chains are calculated by iteration method in this paper.Their thermodynamical proper-ties at low temperature are studied.It is found that when the temperature tends to zero,thethermodynamical quantities as the functions of B/J have the discontinue at some critical val-ues.The ground state configurations of systems at the different parameter regions are de-scribed and the reasons of singularity are explained. |
