In this work,we study the interaction between two colloidal particles in a liquid crystal that is in the isotropic phase.The interaction is caused by surface-induced polarization of the liquid crystal molecules in the vicinity of the particles.We find that the interaction is short-ranged in both 2D and 3D geometry.Under symmetric homeotropic anchoring conditions,the interaction is repulsive.While under anti-symmetric homeotropic anchoring conditions,the interaction is repulsive at short distances but attractive at intermediate distances.The particle size has a strong impact on the effective interaction force.
