Three-body interactions between rods in liquid crystals were calculated. For some configurations, triplet forces match pair forces in strength and range.

Area of Science:

  • Soft Matter Physics
  • Colloidal Science
  • Liquid Crystal Physics

Background:

  • Nematic liquid crystals exhibit unique properties due to anisotropic interactions.
  • Colloidal particles in liquid crystals experience complex effective interactions.
  • Understanding multi-body interactions is crucial for predicting colloidal assembly.

Purpose of the Study:

  • To calculate three-body effective interactions between parallel cylindrical rods in a nematic liquid crystal.
  • To analyze these interactions for collinear, equilateral, and midplane configurations.
  • To compare the magnitude and range of triplet interactions with pair interactions.

Main Methods:

  • Utilizing the Landau-de Gennes free-energy description.
  • Modeling interactions between three parallel cylindrical colloidal particles.

  • Analyzing specific geometric arrangements of the particles.

    • Main Results:

    • Effective three-body interactions were successfully calculated for the specified configurations.
    • In equilateral and midplane arrangements, triplet interactions were found to be significant.
    • The magnitude and range of these triplet interactions were comparable to pairwise forces.

    Conclusions:

    • The Landau-de Gennes model provides a framework for understanding multi-body colloidal interactions in liquid crystals.
    • Triplet interactions can be as influential as pair interactions in certain configurations.
    • This research contributes to the understanding of colloidal self-assembly in liquid crystalline media.
