二维Fibonacci准晶伊辛模型的蒙特卡罗计算

MONTE CARLO CALCULATION OF THE ISING MODEL ON THE TWO-DIMENSIONAL FIBONACCI QUASILATTICE

利用蒙特卡罗方法研究了二维Fibonacci准晶伊丰模型的相变问题．同正方格子相比．二维Fibonacci格子发生顺磁-铁磁相变的临界点向低温方向偏移，对此结果给出了合理解释．

The Ising model on the two-dimensional Fihonacci quasilattice is studied by meanso f the Monte carlo method. It is shown that the paramagnetic -- ferromagnetic phase transition canalso take place on the two -- dimensional Fihonacci quasllattice, but the critical point has shifted inthe direction of lower temperature, comparing with the square lattice, and an explanation is givenfor this point of the results.
