Swimming Bacteria in Confined Chromonic Liquid Crystal: Modeling and Analysis
Mathematical Biology| Speaker: | Cora Brown, University of Minnesota and C.H. Robinson |
| Location: | Zoom |
| Start time: | Mon, Mar 8 2021, 2:10PM |
Experiments in living liquid crystals, the mixture of bacteria and an underlying nematic liquid crystal, present remarkable features, including the ability of bacteria to transport cargoes and the formation of patterns in the system to direct the motion of the bacteria. This talk will present a continuum mixture model for the living liquid crystal system, which derives elements from several mathematical sources, including the nematic flow theory of Ericksen and Leslie, the mixture theory of Flory and Huggins, and the anisotropic active theory of Ramaswamy. We will discuss stability analysis of the zero solution in a thin channel and planar flow solutions which accurately reproduce experimental results.
