Shaping nematic order in bacterial films with single-cell resolution patterning
Matthias Le Bec, Guillem Pérez MartÃn, Cameron Boggon +7
Bacterial colonies composed of elongated cells form active nematic fluids that spontaneously self-organise into ordered domains of aligned cells and exhibit self-generated chaotic…
Transition to the buoyancy dominated regime in a planar temporal forced plume
G. Boga, A. Cimarelli, M. Crialesi Esposito +3
We study the transition from momentum- to buoyancy-dominated regime in temporal jets forced by gravity. From the conservation of the thermal content and of the volume flux, we deve…
Hydrodynamic stability and pattern formation in hexatic epithelial layers
Josep-Maria Armengol-Collado, Leonardo Puggioni, Livio N. Carenza +1
We investigate the hydrodynamic stability and the formation of patterns in a continuum model of epithelial layers, able to account for the interplay between mechanical activity, la…
Collective migration and topological phase transitions in confluent epithelia
Leonardo Puggioni, Dimitrios Krommydas, Luca Giomi
Collective epithelial migration leverages on topological rearrangements of the intercellular junctions, which allow cells to intercalate without loosing confluency. In silico studi…
