Studi Perubahan Fase Spin Glass Model Ising pada Kisi Kuasi Dua Dimensi

Critical nature of Ising model Spin Glass on two dimension quasi-lattices had been studied through the Monte-Carlo simulation. Because of its metastability characteristic, consequently, it used Replica-Exchange Algorithm. Physical quantities which was calculated include heat capacity and overlapping parameter. Critical temperature estimation was obtained through the heat capacity analysis, whereas the presence of Spin Glass phase was obtained through the overlapping parameter value. Two previous researches show that both of high and low dimension system can and cannot actually accomodate Spin Glass phase. The simulation results show the fact that the dimension addition by fractal method (quasi-lattices) can accomodate Spin Glass phase
