TL;DR
This paper calculates three-body effective interactions among cylindrical rods in nematic liquid crystals using Landau-de Gennes theory, revealing that in certain configurations these triplet interactions are comparable to pair interactions.
Contribution
It provides the first detailed calculation of three-body interactions in nematic colloids, highlighting their significance in specific arrangements.
Findings
Triplet interactions are comparable to pair interactions in certain configurations.
Effective triplet interactions are of similar magnitude and range as pair interactions.
Configurations considered include collinear, equilateral, and midplane arrangements.
Abstract
Three-body effective interactions emerging between parallel cylindrical rods immersed in a nematic liquid crystals are calculated within the Landau-de Gennes free energy description. Collinear, equilateral and midplane configurations of the three colloidal particles are considered. In the last two cases the effective triplet interaction is of the same magnitude and range as the pair one.
