Shaping nematic order in bacterial films with single-cell resolution patterning
Matthias Le Bec, Guillem Pérez Martín, 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…
Orientational order and topological defects in a dilute solutions of rodlike polymers at low Reynolds number
Leonardo Puggioni, Stefano Musacchio
The relationship between the polymer orientation and the chaotic flow, in a dilute solution of rigid rodlike polymers at low Reynolds number, is investigated by means of direct num…
Flocking turbulence of microswimmers in confined domains
Leonardo Puggioni, Guido Boffetta, Stefano Musacchio
We extensively study the Toner-Tu-Swift-Hohenberg model of motile active matter by means of direct numerical simulations in a two-dimensional confined domain. By exploring the spac…
Giant vortex dynamics in confined active turbulence
L. Puggioni, G. Boffetta, S. Musacchio
We report the numerical evidence of a new state of active turbulence in confined domains. By means of extensive numerical simulations of the Toner-Tu-Swift-Hohenberg model for dens…
Enhancement of drag and mixing in a dilute solution of rodlike polymers at low Reynolds numbers
Leonardo Puggioni, Guido Boffetta, Stefano Musacchio
We study the dynamics of a dilute solution of rigid rodlike polymers in a viscous fluid at low Reynolds number by means of numerical simulations of a simple rheological model. We s…
Conformal invariance of weakly compressible two-dimensional turbulence
Leonardo Puggioni, Alexei G. Kritsuk, Stefano Musacchio +1
We study conformal invariance of vorticity clusters in weakly compressible two-dimensional turbulence at low Mach numbers. On the basis of very high resolution direct numerical sim…
