Active Bound States Arise From Transiently Nonreciprocal Pair Interactions
Luca Cocconi, Henry Alston, Thibault Bertrand
Static nonreciprocal forces between particles generically drive persistent motion reminiscent of self-propulsion. Here, we demonstrate that reciprocity-breaking fluctuations about…
Machine learning topological defects in confluent tissues
Andrew Killeen, Thibault Bertrand, Chiu Fan Lee
Active nematics is an emerging paradigm for characterising biological systems. One aspect of particularly intense focus is the role active nematic defects play in these systems, as…
Modeling growing confluent tissues using a lattice Boltzmann method: interface stability and fluctuations
Andrew Killeen, Benjamin Partridge, Thibault Bertrand +1
Tissue growth underpins a wide array of biological and developmental processes, and numerical modeling of growing systems has been shown to be a useful tool for understanding these…
Intermittent Attractive Interactions Lead to Microphase Separation in Non-motile Active Matter
Henry Alston, Andrew O. Parry, Raphaël Voituriez +1
Non-motile active matter exhibits a wide range of non-equilibrium collective phenomena yet examples are crucially lacking in the literature. We present a microscopic model inspired…
Polar Fluctuations Lead to Extensile Nematic Behavior in Confluent Tissues
Andrew Killeen, Thibault Bertrand, Chiu Fan Lee
How can a collection of motile cells, each generating contractile nematic stresses in isolation, become an extensile nematic at the tissue-level? Understanding this seemingly contr…
Adhesion as a trigger of droplet polarization in flowing emulsions
Iaroslava Golovkova, Lorraine Montel, Franck Pan +4
Tissues are subjected to large external forces and undergo global deformations during morphogenesis. We use synthetic analogues of tissues to study the impact of cell-cell adhesion…
