Topological active matter

S Shankar, A Souslov, MJ Bowick, MC Marchetti… - Nature Reviews …, 2022 - nature.com
In active matter systems, individual constituents convert energy into non-conservative forces
or motion at the microscale, leading to morphological features and transport properties that …

Physics of liquid crystals in cell biology

A Doostmohammadi, B Ladoux - Trends in cell biology, 2022 - cell.com
The past decade has witnessed a rapid growth in understanding of the pivotal roles of
mechanical stresses and physical forces in cell biology. As a result, an integrated view of …

Topological defects in the nematic order of actin fibres as organization centres of Hydra morphogenesis

Y Maroudas-Sacks, L Garion, L Shani-Zerbib… - Nature Physics, 2021 - nature.com
Animal morphogenesis arises from the complex interplay between multiple mechanical and
biochemical processes with mutual feedback. Developing an effective, coarse-grained …

Theory of defect-mediated morphogenesis

LA Hoffmann, LN Carenza, J Eckert, L Giomi - Science advances, 2022 - science.org
Growing experimental evidence indicates that topological defects could serve as organizing
centers in the morphogenesis of tissues. Here, we provide a quantitative explanation for this …

Patterning of morphogenetic anisotropy fields

Z Wang, MC Marchetti, F Brauns - Proceedings of the …, 2023 - National Acad Sciences
Orientational order, encoded in anisotropic fields, plays an important role during the
development of an organism. A striking example of this is the freshwater polyp Hydra, where …

Topological defect-mediated morphodynamics of active–active interfaces

DQ Zhang, PC Chen, ZY Li… - Proceedings of the …, 2022 - National Acad Sciences
Physical interfaces widely exist in nature and engineering. Although the formation of passive
interfaces is well elucidated, the physical principles governing active interfaces remain …

Phase-field modeling of complex interface dynamics in drop-laden turbulence

A Roccon, F Zonta, A Soldati - Physical Review Fluids, 2023 - APS
Turbulent flows laden with large, deformable drops are ubiquitous in nature and in a wide
range of industrial processes. Prediction of the interactions between drops, which deform …

Morphology of active deformable 3D droplets

LJ Ruske, JM Yeomans - Physical Review X, 2021 - APS
We numerically investigate the morphology and disclination line dynamics of active nematic
droplets in three dimensions. Although our model incorporates only the simplest possible …

Entropy production fluctuations encode collective behavior in active matter

T GrandPre, K Klymko, KK Mandadapu, DT Limmer - Physical Review E, 2021 - APS
We derive a general lower bound on distributions of entropy production in interacting active
matter systems. The bound is tight in the limit that interparticle correlations are small and …

Harnessing the power of chemically active sheets in solution

RK Manna, A Laskar, OE Shklyaev… - Nature Reviews …, 2022 - nature.com
In living organisms, diffusing chemicals react with soft tissue to actuate a range of
mechanical actions, such as periodic pulsations or net motion. Inspired by this biological …
