Controlling Turbulent Flows in Compressible Active Liquid Crystals
Dimitrios Krommydas, Paarth Gulati, Aparna Baskaran +1
Motivated by experiments on light-patterned, quasi-2D active suspensions that exhibit large density variations, we develop a continuum theory of compressible active nematics--suspe…
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…
Quasi long-ranged order in two-dimensional active liquid crystals
Livio Nicola Carenza, Josep-Maria Armengol-Collado, Dimitrios Krommydas +1
Quasi-long ranged order is the hallmark of two-dimensional liquid crystals. At equilibrium, this property implies that the correlation function of the local orientational order par…
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…
