Active topological strings in renewing nematopolar fluids
Alberto Dinelli, Ludovic Dumoulin, Karsten Kruse
Active matter often simultaneously exhibits different kinds of orientational order and, in many cases of biological interest, undergoes continuous material renewal. In renewing nem…
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…
Defect states in compressible active polar fluids with turnover
Ludovic Dumoulin, Carles Blanch-Mercader, Karsten Kruse
Biological active matter like the cytoskeleton or tissues are characterized by their ability to transform chemical energy into mechanical stress. In addition, it often exhibits ori…
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…
