Cooperative effect of local active stresses on the macroscopic contractility of elastic fiber networks
Abhinav Kumar, David A. Quint, Kinjal Dasbiswas
The collective action of actively contractile units embedded in elastic biopolymer networks plays a crucial role in regulating the network's macroscopic mechanical response. Here,…
Gliding microtubules exhibit tunable collective rotation driven by chiral active forces
Madhuvanthi Guruprasad Athani, Nathan Prouse, Niranjan Sarpangala +11
How chirality propagates across scales remains an open question in many biological and synthetic systems. An especially clear manifestation of this propagation is found in in vitro…
Elastic interactions compete with persistent cell motility to drive durotaxis
Subhaya Bose, Haiqin Wang, Xinpeng Xu +2
The directed migration of cells toward stiffer substrate regions or durotaxis is relevant to tissue development and tumor progression. Here, we introduce a phenomenological model f…
Shape Transitions in Network Model of Active Elastic Shells
Ajoy Maji, Kinjal Dasbiswas, Yitzhak Rabin
Morphogenesis involves the transformation of initially simple shapes, such as multicellular spheroids, into more complex shapes. These shape changes are governed by mechanical…
Range and strength of mechanical interactions of force dipoles in elastic fiber networks
Abhinav Kumar, David A. Quint, Kinjal Dasbiswas
Mechanical forces generated by myosin II molecular motors drive diverse cellular processes, most notably shape change, division and locomotion. These forces may be transmitted over…
Optimal mechanical interactions direct multicellular network formation on elastic substrates
Patrick S. Noerr, Jose E. Zamora Alvarado, Farnaz Golnaraghi +3
Cells self-organize into functional, ordered structures during tissue morphogenesis, a process that is evocative of colloidal self-assembly into engineered soft materials. Understa…
Collective states of active particles with elastic dipolar interactions
Subhaya Bose, Patrick S. Noerr, Ajay Gopinathan +2
Many types of mammalian cells exert active contractile forces and mechanically deform their elastic substrate, to accomplish biological functions such as cell migration. These subs…
Modeling mechanochemical pattern formation in elastic sheets of biological matter
Andrei Zakharov, Kinjal Dasbiswas
Inspired by active shape morphing in developing tissues and biomaterials, we investigate two generic mechanochemical models where the deformations of a thin elastic sheet are drive…
Self-organization and shape change by active polarization in nematic droplets
Fabian Jan Schwarzendahl, Pierre Ronceray, Kimberly L. Weirich +1
Active forces occurring within cells can drive crucial biological processes that involve spontaneous organization and shape change, such as cell division. Motivated by recent in vi…
Mechanochemical induction of wrinkling morphogenesis on elastic shells
Andrei Zakharov, Kinjal Dasbiswas
Morphogenetic dynamics of tissue sheets require coordinated cell shape changes regulated by global patterning of mechanical forces. Inspired by such biological phenomena, we propos…
Nucleation and shape dynamics of model nematic tactoids around adhesive colloids
Nicholas B. Ludwig, Kimberly Weirich, Eli Alster +4
Recent experiments have shown how nematically-ordered tactoid shaped actin droplets can be reorganized and divided by the action of myosin molecular motors. In this paper, we consi…
Describing screening in dense ionic fluids with a charge-frustrated Ising model
Nicholas B. Ludwig, Kinjal Dasbiswas, Dmitri V. Talapin +1
Charge correlations in dense ionic fluids give rise to novel effects such as long-range screening and colloidal stabilization which are not predicted by the classic Debye-Huckel th…
Topological waves in fluids with odd viscosity
Anton Souslov, Kinjal Dasbiswas, Michel Fruchart +2
Fluids in which both time-reversal and parity are broken can display a dissipationless viscosity that is odd under each of these symmetries. Here, we show how this odd viscosity ha…
Theory of epithelial cell shape transitions induced by mechanoactive chemical gradients
Kinjal Dasbiswas, Edouard Hannezo, Nir. S. Gov
Cell shape is determined by a balance of intrinsic properties of the cell as well as its mechanochemical environment. Inhomogeneous shape changes underly many morphogenetic events…
Topological localization in out-of-equilibrium dissipative systems
Kinjal Dasbiswas, Kranthi K. Mandadapu, Suriyanarayanan Vaikuntanathan
In this paper we report that notions of topological protection can be applied to stationary configurations that are driven far from equilibrium by active, dissipative processes. We…
Dislocation-induced superfluidity in a model supersolid
D. Goswami, K. Dasbiswas, C. -D. Yoo +1
Motivated by recent experiments on the supersolid behavior of He, we study the effect of an edge dislocation in promoting superfluidity in a Bose crystal. Using Landau theory,…
Bound states of edge dislocations: The quantum dipole problem in two dimensions
K. Dasbiswas, D. Goswami, C. -D. Yoo +1
We investigate bound state solutions of the 2D Schrödinger equation with a dipole potential originating from the elastic effects of a single edge dislocation. The knowledge of thes…
