Strain rate controls alignment in growing bacterial monolayers Open
Growing monolayers of rod-shaped bacteria exhibit local alignment similar to extensile active nematics. When confined in a channel or growing inward from a ring, the local nematic order of these monolayers changes to a global ordering with…

Stress and alignment response to curved obstacles in growing bacterial monolayers Open
Monolayers of growing bacteria, confined within channel geometries, exhibit self-organization into a highly aligned laminar state along the axis of the channel. Although this phenomenon has been observed in experiments and simulations unde…

Growth-induced phase changes in swimming bacteria at finite liquid interfaces Open
We introduce a system of bacteria confined to a finite 2D oil-water interface and driven on two distinct time scales by motility and by growth. The combined effect of activity on different time scales creates transitions between several co…

Microdomains and Stress Distributions in Bacterial Monolayers on Curved Interfaces Open
Monolayers of growing non-motile rod-shaped bacteria act as active nematic materials composed of hard particles rather than the flexible components of other commonly studied active nematics. The organization of these granular monolayers ha…

Self-organized dynamics and the transition to turbulence of confined active nematics Open
Significance Topological defects are a ubiquitous feature of diverse materials ranging from superconductors to liquid crystals. In contrast to conventional materials where defects produce static field configurations, topological defects in…

Insensitivity of active nematic liquid crystal dynamics to topological constraints Open
Confining a liquid crystal imposes topological constraints on the orientational order, allowing global control of equilibrium systems by manipulation of anchoring boundary conditions. In this article, we investigate whether a similar strat…
