We investigate, by Monte Carlo simulation, the effect of the steepness of the short range repulsive potential on mesostructure formation in dipolar particles submitted to a strong external field. Columnar clusters made of several dipolar chains are only observed when the short-range potential is sufficiently steep. The confinement of the dipolar liquid in a slit geometry instead of bulk conditions suppresses the formation of columns.
我们通过蒙特卡罗模拟研究了短程排斥势陡峭程度对强外场下偶极粒子介观结构形成的影响。只有当短程势足够陡峭时,才会观察到由几条偶极链组成的柱状团簇。在狭缝几何形状而不是在体条件下限制偶极液体,会抑制柱状结构的形成。
