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…
Beyond Dipolar Activity: Quadrupolar Stress Drives Collapse of Nematic Order on Frictional Substrates
Aleksandra Ardaševa, Ignasi Vélez-Cerón, Martin Cramer Pedersen +3
The field of active nematics has traditionally employed descriptions based on dipolar activity, with interactions that align along a single axis. However, it has been theoretically…
Elasticity tunes mechanical stress localization around active topological defects
Lasse Bonn, Aleksandra Ardaševa, Amin Doostmohammadi
Mechanical stresses are increasingly found to be associated with various biological functionalities. At the same time, topological defects are being identified across a diverse ran…
Bridging microscopic cell dynamics to nematohydrodynamics of cell monolayers
Aleksandra Ardaševa, Romain Mueller, Amin Doostmohammadi
It is increasingly being realized that liquid-crystalline features can play an important role in the properties and dynamics of cell monolayers. Here, we present a cell-based model…
Fluctuation-induced dynamics of nematic topological defects
Lasse Bonn, Aleksandra Ardaseva, Romain Mueller +2
Topological defects are increasingly being identified in various biological systems, where their characteristic flow fields and stress patterns are associated with continuous activ…
