Active colloidal rafts perform swimming strokes that propel their host droplets
Airi N. Kato, Julien Brémont, Etienne Harté +3
Active particles confined in droplets can set their host droplet into motion. This phenomenon is usually attributed to direct hydrodynamic forcing by the enclosed particles. Here w…
Active-gel Theory for Multicellular Migration of Polar Cells in the Extra-cellular Matrix
Ram M. Adar, Jean-François Joanny
We formulate an active-gel theory for multicellular migration in the extra-cellular matrix (ECM). The cells are modeled as an active, polar solvent, and the ECM as a viscoelastic s…
Spontaneous flow created by active topological defects
Louis Brézin, Thomas Risler, Jean-François Joanny
Topological defects are at the root of the large-scale organization of liquid crystals. In two-dimensional active nematics, two classes of topological defects of charges …
Rheology of 2D vertex model
Doron Grossman, Jean-Francois Joanny
The mechanical properties of tissues play an essential role for all tissue properties such as cell division, and differentiation or morphogenesis. Here, we study theoretically the…
Instabilities and geometry of growing tissues
Doron Grossman, Jean-Francois Joanny
We derive a course grained, continuum model of the 2D vertex model, applicable for different underlying geometries, and allowing for analytical analysis of an otherwise numerical m…
Steric interactions and out-of-equilibrium processes control the internal organization of bacteria
Ander Movilla Miangolarra, Sophia Hsin-Jung Li, Jean-François Joanny +2
Despite the absence of a membrane-enclosed nucleus, the bacterial DNA is typically condensed into a compact body - the nucleoid. This compaction influences the localization and dyn…
