    摘要Living liquid crystal (LLC) is a class of active matter that combines active particles such as swimming bacteria with a lyotropic liquid crystal. The interaction of active motion with orientation order of liquid crystal (LC) leads to striking optical, hydrodynamical, and electrical properties of LLC, as well as collective behavior and emergence of intriguing patterns. In this work, we aim to understand how the orientation order of liquid crystal affects the motion of a single swimmer. We study a nonlinearly coupled PDE model which combines the well-known Edwards-Beris model for liquid crystal hydrodynamics with a squirmer model describing active swimmer. Analytical and numerical study reveals the competition between the dissipation dynamics of liquid crystal flow and the active propulsion. Numerical results show how the shape and anchoring strength may affect the stable squirming direction. This is a joint work with Hai Chi, Leonid Berlyand, and Igor Aronson.
