Theory of nematic and polar active fluid surfaces
Guillaume Salbreux, Frank Jülicher, Jacques Prost +1
We derive a fully covariant theory of the hydrodynamics of nematic and polar active surfaces, subjected to internal and external forces and torques. We study the symmetries of pola…
Active morphogenesis of patterned epithelial shells
Diana Khoromskaia, Guillaume Salbreux
Shape transformations of epithelial tissues in three dimensions, which are crucial for embryonic development or in vitro organoid growth, can result from active forces generated wi…
Scaling of Entropy Production under Coarse Graining in Active Disordered Media
Luca Cocconi, Guillaume Salbreux, Gunnar Pruessner
Entropy production plays a fundamental role in the study of non-equilibrium systems by offering a quantitative handle on the degree of time-reversal symmetry breaking. It depends c…
Field theory of survival probabilities, extreme values, first passage times, and mean span of non-Markovian stochastic processes
Benjamin Walter, Gunnar Pruessner, Guillaume Salbreux
We provide a perturbative framework to calculate extreme events of non-Markovian processes, by mapping the stochastic process to a two-species reaction diffusion process in a Doi-P…
Tissue hydraulics: physics of lumen formation and interaction
Alejandro Torres-Sánchez, Max Kerr Winter, Guillaume Salbreux
Lumen formation plays an essential role in the morphogenesis of tissues during development. Here we review the physical principles that play a role in the growth and coarsening of…
First passage time distribution of active thermal particles in potentials
Benjamin Walter, Gunnar Pruessner, Guillaume Salbreux
We introduce a perturbative method to calculate all moments of the first-passage time distribution in stochastic one-dimensional processes which are subject to both white and colou…
Stability and roughness of interfaces in mechanically-regulated tissues
John J. Williamson, Guillaume Salbreux
Cell division and death can be regulated by the mechanical forces within a tissue. We study the consequences for the stability and roughness of a propagating interface, by analysin…
Mechanics of active surfaces
Guillaume Salbreux, Frank Jülicher
We derive a fully covariant theory of the mechanics of active surfaces. This theory provides a framework for the study of active biological or chemical processes at surfaces, such…
Triangles bridge the scales: Quantifying cellular contributions to tissue deformation
Matthias Merkel, Raphaël Etournay, Marko Popović +3
In this article, we propose a general framework to study the dynamics and topology of cellular networks that capture the geometry of cell packings in two-dimensional tissues. Such…
Active dynamics of tissue shear flow
Marko Popović, Amitabha Nandi, Matthias Merkel +4
We present a hydrodynamic theory to describe shear flows in developing epithelial tissues. We introduce hydrodynamic fields corresponding to state properties of constituent cells a…
Role of turn-over in active stress generation in a filament network
Tetsuya Hiraiwa, Guillaume Salbreux
We study the effect of turnover of cross linkers, motors and filaments on the generation of a contractile stress in a network of filaments connected by passive crosslinkers and sub…
Optimal chemotaxis in animal cell intermittent migration
Pawel Romanczuk, Guillaume Salbreux
Animal cells can sense chemical gradients without moving, and are faced with the challenge of migrating towards a target despite noisy information on the target position. Here we d…
Spontaneous oscillations from turnover of an elastic contractile material
Kai Dierkes, Angughali Sumi, Jérôme Solon +1
Single and collective cellular oscillations involving the actomyosin cytoskeleton have been observed in numerous biological systems. We show here that a generic model of a contract…
