The Jammed Phase of Infinitely Persistent Active Matter
M. C. Gandikota, Rituparno Mandal, Pinaki Chaudhuri +2
We study an extreme active matter system, which is essentially a dense assembly of athermal, soft and infinitely persistent active particles. Using extensive numerical simulations…
Rectification of stress by fiber networks: Manifestation of non-linear screening through self-organized buckling
Kanaya Malakar, Albert Countryman, Bulbul Chakraborty
Force transmission at large length scales is crucial for such biological functions as cell motility and morphogenesis. The networks that transmit these forces are malleable, patter…
Stress Response of Jammed Solids: Prestress and Screening
Surajit Chakraborty, Jishnu N. Nampoothiri, Subhro Bhattacharjee +2
Unlike classical elasticity, where stresses arise from deformations relative to a stress-free reference configuration, rigidity in amorphous systems is maintained by disordered for…
Pinch-point Singularities in Stress-Stress Correlations Reveal Rigidity in Colloidal Gels
Albert Countryman, H. A. Vinutha, Fabiola Diaz Ruiz +3
We demonstrate that the spatial correlations of microscopic stresses in 2D model colloidal gels obtained in computer simulations can be quantitatively described by the predictions…
Rigid clusters in shear-thickening suspensions: a nonequilibrium critical transition
Aritra Santra, Michel Orsi, Bulbul Chakraborty +1
The onset and growth of rigid clusters in a two-dimensional (2D) suspension in shear flow are studied by numerical simulations. The suspension exhibits the lubricated-to-frictional…
Origin of Corrections to Mean-field at the Onset of Unjamming
Mitchell Mailman, Bulbul Chakraborty
We present a detailed analysis of the unjamming transition in 2D frictionless disk packings using a static correlation function that has been widely used to study disordered system…
