β¦ Synopsis
The relaxation process of C 60 molecule around glass transition temperature is studied by Monte Carlo simulation, using a new model of the energy barrier of molecule between two orientational states in C 60 crystal, which depends on the state of neighboring molecules. The results show that the relaxation is slightly non-exponential, which can be fit to Kohlrausch-Williams-Watts (KWW) function. The non-exponential factor b is 0:962 ^0:002; and this value reproduces the experimental data that has not been explained before.

In this paper we present results of the Monte Carlo simulation of a 2D nematic liquid crystal model in the presence of an externally applied electric field. The molecular interactions were described by the Lebwohl -Lasher Hamiltonian. The boundary conditions employed in the simulations corresponded
