Disorder-induced persistent random motion and trapping of microswimmers
Mirko Residori, Sebastian Aland, Christina Kurzthaler
Microorganisms ofter move in confined, disordered environments, where hydrodynamic couplings can modify their transport behavior. Using extensive finite-element simulations, we inv…
From Heteropolymer Stiffness Distributions to Effective Homopolymers: A Conformational Analysis of Intrinsically Disordered Proteins
Yannick Witzky, Friederike Schmid, Arash Nikoubashman
Synthetic copolymers and biopolymers, such as polypeptides and double-stranded DNA, often exhibit strong variations in bending stiffness along their contour, which can significantl…
Probe particles in odd active viscoelastic fluids: how activity and dissipation determine linear stability
Charlie Duclut, Stefano Bo, Ruben Lier +3
Odd viscoelastic materials are constrained by fewer symmetries than their even counterparts. The breaking of these symmetries allow these materials to exhibit different features, w…
Charge separation at liquid interfaces
Arghya Majee, Christoph A. Weber, Frank Jülicher
We present a theory for phase-separated liquid coacervates with salt, taking into account spatial heterogeneities and interfacial profiles. We find that charged layers of alternati…
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…
Coordinated motion of epithelial layers on curved surfaces
Lea Happel, Axel Voigt
Coordinated cellular movements are key processes in tissue morphogenesis. Using a cell-based modeling approach we study the dynamics of epithelial layers lining surfaces with const…
Theory of rheology and aging of protein condensates
Ryota Takaki, Louise Jawerth, Marko Popović +1
Biological condensates are assemblies of proteins and nucleic acids that form membraneless compartments in cells and play essential roles in cellular functions. In many cases they…
The interplay of geometry and coarsening in multicomponent lipid vesicles under the influence of hydrodynamics
Elena Bachini, Veit Krause, Axel Voigt
We consider the impact of surface hydrodynamics on the interplay between curvature and composition in coarsening processes on model systems for biomembranes. This includes scaling…
Spontaneous flow instabilities of active polar fluids in three dimensions
Abhinav Singh, Quentin Vagne, Frank Jülicher +1
Active polar fluids exhibit spontaneous flow when sufficient active stress is generated by internal molecular mechanisms. This is also referred to as an active Fréedericksz transit…
Random traction yielding transition in epithelial tissues
Aboutaleb Amiri, Charlie Duclut, Frank Jülicher +1
We investigate how randomly oriented cell traction forces lead to fluidisation in a vertex model of epithelial tissues. We find that the fluidisation occurs at a critical value of…
Odd Cosserat elasticity in active materials
Piotr Surówka, Anton Souslov, Frank Jülicher +1
Stress-strain constitutive relations in solids with an internal angular degree of freedom can be modelled using Cosserat (also called micropolar) elasticity. In this paper, we expl…
Broken living layers: dislocations in active smectics
Frank Julicher, Jacques Prost, John Toner
We show that dislocations in active 2d smectics with underlying rotational symmetry are always unbound in the presence of noise, meaning the active smectic phase does not exist for…
Lift force in odd compressible fluids
Ruben Lier, Charlie Duclut, Stefano Bo +3
We compute the response matrix for a tracer particle in a compressible fluid with odd viscosity living on a two-dimensional surface. Unlike the incompressible case, we find that an…
Effects of local curvature on epithelia tissue -- coordinated rotational movement and other spatiotemporal arrangements
Lea Happel, Dennis Wenzel, Axel Voigt
Coordinated movements of epithelia tissue are linked with active matter processes. We here consider the influence of curvature on the spatiotemporal arrangements and the shapes of…
Passive odd viscoelasticity
Ruben Lier, Jay Armas, Stefano Bo +3
Active chiral viscoelastic materials exhibit elastic responses perpendicular to the applied stresses, referred to as odd elasticity. We use a covariant formulation of viscoelastici…
The impact of contact inhibition on collective cell migration and proliferation
Harish P. Jain, Dennis Wenzel, Axel Voigt
Contact inhibition limits migration and proliferation of cells in cell colonies. We consider a multiphase field model to investigate the growth dynamics of a cell colony, composed…
Active nematodynamics on curved surfaces -- the influence of geometric forces on motion patterns of topological defects
Michael Nestler, Axel Voigt
We derive and numerically solve a surface active nematodynamics model. We validate the numerical approach on a sphere and analyse the influence of hydrodynamics on the oscillatory…
Multiphase field models for collective cell migration
Dennis Wenzel, Axel Voigt
Confluent cell monolayers and epithelia tissues show remarkable patterns and correlations in structural arrangements and actively-driven collective flows. We simulate these propert…
Coarse-grained curvature tensor on polygonal surfaces
Charlie Duclut, Aboutaleb Amiri, Joris Paijmans +1
Using concepts from integral geometry, we propose a definition for a local coarse-grained curvature tensor that is well-defined on polygonal surfaces. This coarse-grained curvature…
Active viscoelasticity of odd materials
Debarghya Banerjee, Vincenzo Vitelli, Frank Jülicher +1
The mechanical response of active media ranging from biological gels to living tissues is governed by a subtle interplay between viscosity and elasticity. In this Letter, we genera…
Liquid Crystals on Deformable Surfaces
Ingo Nitschke, Sebastian Reuther, Axel Voigt
Liquid crystals with molecules constrained to the tangent bundle of a curved surface show interesting phenomena resulting from the tight coupling of the elastic and bulk free energ…
