Run-and-tumble chemotaxis using reinforcement learning
Ramesh Pramanik, Shradha Mishra, Sakuntala Chatterjee
Bacterial cells use run-and-tumble motion to climb up attractant concentration gradient in their environment. By extending the uphill runs and shortening the downhill runs the cell…
From Flocking to Condensation: Collective Dynamics in Binary Chiral Active Matter
Divya Kushwaha, Shradha Mishra
Many microswimmers are inherently chiral, and this chirality can introduce fascinating behaviors in a collection of microswimmers. The dynamics become even more intriguing when two…
Synchronized Rotations of Active Particles on Chemical Substrates
Pathma Eswaran, Shradha Mishra
Many microorganisms use chemical `signaling' - a quintessential self-organizing strategy in non-equilibrium - that can induce spontaneous aggregation and coordination in behavior.…
Kinetics and steady state of polar flock with birth and death
Pratikshya Jena, Shradha Mishra
We study a collection of polar self-propelled particles or polar flock on a two dimensional substrate with birth and death. Most of the previous studies of polar flock with birth a…
Ordering kinetics in active polar fluid
Shambhavi Dikshit, Shradha Mishra
We model the active polar fluid as a collection of orientable objects supplied with active stresses and momentum damping coming from the viscosity of bulk fluid medium. The growth…
Active Brownian particles can mimic the pattern of the substrate
Pawan Kumar Mishra, Ajeya Krishna, Shradha Mishra
Active Brownian particles (ABPs) are termed out to be a successful way of modeling the moving microorganism on the substrate. In recent studies, it is shown that such organisms can…
