Collective epithelial migration mediated by the unbinding of hexatic defects
Dimitrios Krommydas, Livio Nicola Carenza, Luca Giomi
Collective cell migration in epithelia relies on cell intercalation: a local remodelling of the cellular network that allows neighbouring cells to swap their positions. Unlike foam…
Activity drives self-assembly of passive soft inclusions in active nematics
Ahmet Umut Akduman, Yusuf Sariyar, Giuseppe Negro +1
Active nematics are out-of-equilibrium systems in which energy injection at the microscale drives emergent collective behaviors, from spontaneous flows to active turbulence. While…
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…
Thick liquid crystalline cholesteric shells
Arda Bulut, Yusuf Sariyar, Giuseppe Negro +1
We numerically investigate the phase behavior of thick shells of cholesteric liquid crystals with tangential anchoring at the shell boundary. For achiral liquid crystal, we demonst…
