Chiral Symmetry Breaking in Bacterial Suspensions

ORAL

Abstract

Bacterial suspensions provide a paradigmatic platform for studying the rich collective dynamics of active matter. The complex interplay between single-cell motility, intercellular interactions, and environmental coupling can lead to a variety of self-organized states, from large-scale coherent flows to chaotic turbulence. In this work, we study the collective behavior of dense bacterial suspensions where interplay between cells and their environment plays a significant role. We focus on how such local interactions can break chiral symmetry in the system and give rise to novel, large-scale collective patterns. Our study aims to elucidate the fundamental principles governing this class of self-organization and to explore the connection between microscopic interactions and the emergent macroscopic fluid properties
