ネマチック液晶中の荷電粒子が与える静的、および動的な効果について、Ginzburg-Landau理論の枠組を用いて議論する。(i)ネマチック相にある液晶に荷電粒子を配した場合の、配向秩序の変形、およびその結果としての欠陥生成について調べた。特に荷電粒子の及ぼす寄与が強い場合、粒子近傍で電荷誘起のアンカリング現象が期待される。(ii)定常電場、および振動電場を与えた場合の、ネマチック液晶中の荷電粒子の運動について調べた。我々の数値計算の結果は、電荷の効果が顕著になるに従い、移動度が小さくなることを予測する。これは、電荷の効果が強くなるにつれ、配向秩序が変形する空間領域が拡大するため、有効的な流体半径が増大すると理解できよう。また、多数の荷電粒子が液晶に浸されている場合の複雑な現象に付いても、併せて報告したい。
