Nematic ordering in active fluids driven by substrate deformations: Mechanisms and patterning regimes
Varun Venkatesh, Amin Doostmohammadi
The interplay between active matter and its environment is central to understanding emergent behavior in biological and synthetic systems. Here, we show that coupling active nemati…
Hydrodynamic bend instability of motile particles on a substrate
Sameer Kumar, Niels de Graaf Sousa, Amin Doostmohammadi
The emergence of hydrodynamic bend instabilities in ordered suspensions of active particles is widely observed across diverse living and synthetic systems, and is considered to be…
Identifying non-equilibrium fluctuations in Intracellular Motion Using Recurrent Neural Networks
Tomas Basile, Natascha Leijnse, Malte Slot Lauridsen +3
Distinguishing active from passive dynamics is a fundamental challenge in understanding the motion of living cells and other active matter systems. Here, we introduce a framework t…
Anti-hyperuniform Critical States of Active Topological Defects
Simon Guldager Andersen, Tianxiang Ma, Makito F. Katsume +4
Topological defects are fundamental to the collective dynamics of non-equilibrium systems and in active matter, mediating spontaneous flows, dynamic self-organization, and emergent…
Self-propulsive active nematics
Niels de Graaf Sousa, Simon Guldager Andersen, Aleksandra Ardaševa +1
Increasing evidence suggests that active matter exhibits instances of mixed symmetry that cannot be fully described by either polar or nematic formalism. Here, we introduce a minim…
The Interplay of Polar and Nematic Order in Active Matter: Implications for Non-Equilibrium Physics and Biology
Varun Venkatesh, Niels de Graaf Sousa, Amin Doostmohammadi
Active matter has played a pivotal role in advancing our understanding of non-equilibrium systems, leading to a fundamental shift in the study of biophysical phenomena. The foundat…
