MONTE CARLO SIMULATION STUDY FOR A NEGATIVE DIELECTRIC ANISOTROPY NEMATIC LIQUID CRYSTAL PRESENTING A DEFECT NANOPARTICLE UNDER APPLIED ELECTRIC FIELD CONDITIONS

By using Monte Carlo simulation we study the effect of an electric field on a negative dielectric anisotropy nematic liquid crystal presenting a spherocylindrical shaped particle located inside. We characterize the orientation of the nematic molecules inside the simulation box by means of the scalar and tensorial order parameter, field order parameter and radial order parameter, We also analyze how the system develops a Saturn ring type disclination line having the plane parallel with the direction of the applied electric field.
