Motility destabilizes an absorbing-state flock
Narayan Dutt Sharma, Subroto Mukerjee, Chandan Dasgupta +1
Activity, when it takes the form of motility, is generally seen to promote order in many-body systems. Here we present a one-dimensional lattice model that, in the non-motile limit…
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…
Dynamics of self-organization in dense persistent active matter
Atharva Shukla, Chandan Dasgupta
We consider a two-dimensional athermal binary mixture of Lennard-Jones particles with persistent random active forces. The liquid phase of this system for active forces exceeding a…
Activity-driven sorting, approach to criticality and turbulent flows in dense persistent active fluids
Suman Dutta, Pinaki Chaudhuri, Madan Rao +1
We show that dense active fluids comprising interacting particles with persistent self-propulsion are driven to a non-equilibrium steady state consisting of co-moving particles wit…
Growing length and time scales in activity-mediated glassy dynamics in confluent cell monolayers
Souvik Sadhukhan, Chandan Dasgupta, Saroj Kumar Nandi
Activity-mediated unjamming of a confluent glassy system is crucial for several biological processes, such as embryogenesis and cancer metastasis. During these processes, the cells…
Melting of rods on a sphere via an intermediate hexatic phase
Jaydeep Mandal, Chandan Dasgupta, Prabal K. Maiti
We have studied, using molecular dynamics simulations, the pressure-induced melting in a monolayer of soft repulsive spherocylinders whose centers of mass are constrained to move o…
