Colloidal suspension show interesting phenomena which are mediated by the s
olvent. Recently, colloids in nematic liquid crystal phase used as anisotro
pic solvent have been investigated experimentally and have inspired theoret
ical work[1-3]. In relation to these work, effective pair potential between
spherical colloidal particles suspended in nematic liquid crystals has bee
n suggested[4,5]. The interparticle interact on can cause nontrivial collec
tive behavior that results in formation of new spatial structures in colloi
dal particle systems. We determine these structures by particle dynamics si
mulations using these effective pair-interaction.
