Biological processes such as embryogenesis, wound healing and cancer progression rely
on the ability of epithelial cells to coordinate their mechanical activity over length scales that …

The impact of the intrinsic curvature of in-plane orientationally ordered curved flexible
nematic molecules attached to closed 3D flexible shells was studied numerically. A Helfrich …

A key feature of many living systems, such as bacteria and eukaryotic cells, is their ability to
actively self-propel. Indeed, cellular motility underlies numerous critical biological …

Abstract We leverage the Born–Oppenheimer approximation to present a general
description of topological defects dynamics in p-atic materials on curved surfaces. Focusing …

We investigate the ground-state configurations of two-dimensional liquid crystals with p-fold
rotational symmetry (p-atics) on fixed curved surfaces. We focus on the intrinsic geometry …

T1 transitions, also called cell intercalations, are important sources of fluidization of
epithelial cell monolayers. We use a multiphase field model to quantify this tissue fluidization …

We formulate a hydrodynamic theory of p-atic liquid crystals, namely, two-dimensional
anisotropic fluids endowed with generic p-fold rotational symmetry. Our approach, based on …

Active matter systems evade the constraints of thermal equilibrium, leading to the
emergence of intriguing collective behavior. A paradigmatic example is given by motor …

We formulate a hydrodynamic theory of confluent epithelia: ie monolayers of epithelial cells
adhering to each other without gaps. Taking advantage of recent progresses toward …

Inspired by epithelial morphogenesis, we consider a minimal model for the sha** of a
surface driven by p-atic topological defects. We show that a positive (negative) defect can …
