Local polar order controls mechanical stress and triggers layer formation in developing Myxococcus xanthus colonies
Endao Han, Chenyi Fei, Ricard Alert +4
Colonies of the social bacterium Myxococcus xanthus go through a morphological transition from a thin colony of cells to three-dimensional droplet-like fruiting bodies as a strateg…
Emergent structures and dynamics of cell colonies by contact inhibition of locomotion
Bart Smeets, Ricard Alert, Jiri Pesek +3
Cells in tissues can organize into a broad spectrum of structures according to their function. Drastic changes of organization, such as epithelial-mesenchymal transitions or the fo…
Fluidization and Active Thinning by Molecular Kinetics in Active Gels
David Oriola, Ricard Alert, Jaume Casademunt
We derive the constitutive equations of an active polar gel from a model for the dynamics of elastic molecules that link polar elements. Molecular binding kinetics induces the flui…
Formation of metastable phases by spinodal decomposition
Ricard Alert, Pietro Tierno, Jaume Casademunt
Metastable phases may be spontaneously formed from other metastable phases through nucleation. Here we demonstrate the spontaneous formation of a metastable phase from an unstable…
