两个连续自旋模型联合态密度的Wang-Landau转移矩阵蒙特卡罗模拟

Monte Carlo simulation of joint density of states of two continuous spin models using Wang-Landau-Transition-Matrix Algorithm

Shyamal Bhar, Soumen Kumar Roy

摘要:

用Wang-Landau和Wang-Landau转移矩阵蒙特卡罗方法对一维Lebwohl-Lasher模型和二维XY模型进行了蒙特卡罗模拟。在由能量序参量和能量关联函数组成的二维空间中进行了随机游走,得到了系统的联合态密度。由JDOS计算了序参量、磁化率和关联函数。从两种算法得到的结果之间的协议是非常好的。

英文摘要:

Monte Carlo simulation has been performed in one-dimensional Lebwohl-Lasher model and two dimensional XY-model using the Wang-Landau and the Wang-Landau-Transition-Matrix Monte Carlo methods. Random walk has been performed in the two-dimensional space comprising of energy-order parameter and energy-correlation function and the joint density of states (JDOS) were obtained. From the JDOS the order parameter, susceptibility and correlation function are calculated. Agreement between the results obtained from the two algorithms is very good.
