Athermal fluctuations in disordered crystals
Pappu Acharya, Surajit Sengupta, Bulbul Chakraborty +1
We analyze the fluctuations in particle positions and inter-particle forces in disordered jammed crystals in the limit of weak disorder. We demonstrate that such athermal systems a…
Arrested States in Persistent Active Matter: Gelation without Attraction
Carl Merrigan, Kabir Ramola, Rakesh Chatterjee +3
We explore phase separation and kinetic arrest in a model active colloidal system consisting of self-propelled, hard-core particles with nonconvex shapes. The passive limit of the…
Timescale divergence at the shear jamming transition
H. A. Vinutha, Kabir Ramola, Bulbul Chakraborty +1
We find that in simulations of quasi-statically sheared frictional disks, the shear jamming transition can be characterized by an abrupt jump in the number of force bearing contact…
Shear jamming and fragility in dense suspensions
Ryohei Seto, Abhinendra Singh, Bulbul Chakraborty +2
The phenomenon of shear-induced jamming is a factor in the complex rheological behavior of dense suspensions. Such shear-jammed states are fragile, i.e., they are not stable agains…
Stress Fluctuations in Transient Active Networks
Daniel Goldstein, Sriram Ramaswamy, Bulbul Chakraborty
Inspired by experiments on dynamic extensile gels of biofilaments and motors, we propose a model of a network of linear springs with a kinetics consisting of growth at a prescribed…
