Renormalized mechanics and stochastic thermodynamics of growing vesicles
Jordan L. Shivers, Michael Nguyen, Aaron R. Dinner +2
Uncovering the rules governing the nonequilibrium dynamics of the membranes that define biological cells is of central importance to understanding the physics of living systems. We…
Criticality enhances the reinforcement of disordered networks by rigid inclusions
Jordan L. Shivers, Jingchen Feng, Fred C. MacKintosh
The mechanical properties of biological materials are spatially heterogeneous. Typical tissues are made up of a spanning fibrous extracellular matrix in which various inclusions, s…
Nonlinear Poisson effect in affine semiflexible polymer networks
Jordan L. Shivers, Fred C. MacKintosh
Stretching an elastic material along one axis typically induces contraction along the transverse axes, a phenomenon known as the Poisson effect. From these strains, one can compute…
Motor crosslinking augments elasticity in active nematics
Steven A. Redford, Jonathan Colen, Jordan L. Shivers +8
In active materials, uncoordinated internal stresses lead to emergent long-range flows. An understanding of how the behavior of active materials depends on mesoscopic (hydrodynamic…
Effects of local incompressibility on the rheology of composite biopolymer networks
Anupama Gannavarapu, Sadjad Arzash, Iain Muntz +4
Fibrous networks such as collagen are common in biological systems. Recent theoretical and experimental efforts have shed light on the mechanics of single component networks. Most…
Structural features and nonlinear rheology of self-assembled networks of cross-linked semiflexible polymers
Saamiya Syed, Fred C. MacKintosh, Jordan L. Shivers
Disordered networks of semiflexible filaments are common support structures in biology. Familiar examples include fibrous matrices in blood clots, bacterial biofilms, and essential…
Signatures of irreversibility in microscopic models of flocking
Federica Ferretti, Simon Grosse-Holz, Caroline Holmes +4
Flocking in is a genuine non-equilibrium phenomenon for which irreversibility is an essential ingredient. We study a class of minimal flocking models whose only source of irr…
Strain-controlled critical slowing down in the rheology of disordered networks
Jordan L. Shivers, Abhinav Sharma, Fred C. MacKintosh
Networks and dense suspensions frequently reside near a boundary between soft (or fluid-like) and rigid (or solid-like) regimes. Transitions between these regimes can be driven by…
Shear-induced phase transition and critical exponents in 3D fiber networks
Sadjad Arzash, Jordan L. Shivers, Fred C. MacKintosh
When subject to applied strain, fiber networks exhibit nonlinear elastic stiffening. Recent theory and experiements have shown that this phenomenon is controlled by an underlying m…
Finite size effects in critical fiber networks
Sadjad Arzash, Jordan L. Shivers, Fred C. MacKintosh
Fibrous networks such as collagen are common in physiological systems. One important function of these networks is to provide mechanical stability for cells and tissues. At physiol…
Nonlinear Poisson effect governed by mechanical critical transition
Jordan L. Shivers, Sadjad Arzash, Fred C. MacKintosh
Under extensional strain, fiber networks can exhibit an anomalously large and nonlinear Poisson effect accompanied by a dramatic transverse contraction and volume reduction for app…
Stress-stabilized sub-isostatic fiber networks in a rope-like limit
Sadjad Arzash, Jordan L. Shivers, Albert J. Licup +2
The mechanics of disordered fibrous networks such as those that make up the extracellular matrix are strongly dependent on the local connectivity or coordination number. For biopol…
Scaling theory for mechanical critical behavior in fiber networks
Jordan Shivers, Sadjad Arzash, Abhinav Sharma +1
As a function of connectivity, spring networks exhibit a critical transition between floppy and rigid phases at an isostatic threshold. For connectivity below this threshold, fiber…
Normal stress anisotropy and marginal stability in athermal elastic networks
Jordan Shivers, Jingchen Feng, Abhinav Sharma +1
Hydrogels of semiflexible biopolymers such as collagen have been shown to contract axially under shear strain, in contrast to the axial dilation observed for most elastic materials…
