Motion of Defects in the Phase Ordering Process of Nematic Liquid Crystals

抄録

Dislinations and monopoles in the phase ordering of three-dimensional nematic liquid crystals follwing a quench are numerically investigated. The total length of dislinations decreases as L-- t^{-0.95± 0.07}. Monopoles are not detected except in the early transient regime. It is found that monopoles change to a ring disclination, and rings reconnect to shrink to nothing.
