论文摘要
高精度蒙特卡洛研究已经在包含和相互作用的改良平面Lebwohl lasher模型中进行，其中以及具有三维自旋的第二和第四阶Legendre多项式。使用此模型观察到弱的一阶nematic至各向同性相变。使用Wolff算法进行了广泛的蒙特卡洛模拟，以研究平均能量，顺序参数，有序敏感性，熵和相近相变的特定热量。还估计了过渡温度。
High accuracy Monte Carlo study has been performed in the modified planar Lebwohl Lasher model containing and interaction, where and are second and fourth order Legendre polynomial having three-dimensional spin. Weakly First order Nematic to Isotropic phase transition is observed using this model. Extensive Monte Carlo simulations using Wolff algorithm are performed to investigate the average energy, order parameter, ordering susceptibility, entropy and specific heat near phase transition. Transition temperature is also estimated.
