Spatiotemporal Control of Charge +1 Topological Defects in Polar Active Matter
Birte C. Geerds, Abhinav Singh, Mathieu Dedenon +4
Topological defects are a conspicuous feature of active liquid crystals that have been associated with important morphogenetic transitions in organismal development. Robust develop…
Three-dimensional formulation of curved nematic shells
Mathieu Dedenon
In soft matter, the phase of nematic liquid crystals can be made from anisotropic molecules in single component materials, or as a suspension of mesoscopic nematogens. The later of…
The importance of being discrete -- An agent-based model for active nematics and more
Mathieu Dedenon, Carles Blanch-Mercader, Karsten Kruse +1
We propose an agent-based model of active flexible rods. Inspired by cytoskeletal flows, we introduce activity by an internal flow that contributes to the dissipative forces. The a…
Noise-induced transitions from contractile to extensile active stress in isotropic fluids
Mathieu Dedenon, Karsten Kruse
Tissues of living cells are a prime example of active fluids. There is experimental evidence that tissues generate extensile active stress even though their constituting cells are…
