Mechanochemical topological defects in an active nematic
Physical Review EWe propose a reaction-diffusion system that converts topological information of an active nematic into chemical signals. We show that a curvature-activated reaction dipole is sufficient for creating a system that dynamically senses topology by producing a concentration field possessing local extrema coinciding with $\pm\frac{1}{2}$ defects.

Nématiques cellulaires actifs Des cellules allongées et apolaires cultivées à confluence s'alignent les unes avec les autres. Dans cette thèse, nous utilisons des concepts de la théorie de la matière active ainsi que de la physique des cristaux liquides afin d'étudier quantitativement l'émergence de cet ordre mésoscopique nématique pour
