Homing through Reinforcement Learning
Riya Singh, Pratikshya Jena, Anish Kumar +1
Homing and navigation are fundamental behaviors in biological systems that enable agents to reliably reach a target under uncertainty. We present a Reinforcement Learning (RL) fram…
Unconventional Growth Kinetics and Fractal Interfaces of Colloidal Phase Separation in Active Liquids
Pragya Kushwaha, Pratikshya Jena, Partha Sarathi Mondal +4
Phase separation driven by nonequilibrium fluctuations is a hallmark of both living and synthetic active matter. Unlike equilibrium systems, where ordered states arise from the min…
Competing effect of disorder on phase separation in active systems
Pratikshya Jena, Shambhavi Dikshit, Shradha Mishra
We investigate the impact of random pinned disorder on a collection of self propelled particles. To achieve this, we construct a continuum model by formulating the coupled hydrodyn…
String Formation and Arrested Ordering Kinetics in Nematics Induced by Polar Particles
Pawan Kumar Mishra, Partha Sarathi Mondal, Pratikshya Jena +1
Our study explores the mixture of polar particles in apolar environment. We employ a coarse-grained approach to model the mixture, where polar particles are in minority. The intera…
Spatio-temporal patterns in Growing Bacterial Suspensions
Pratikshya Jena, Shradha Mishra
The field of active matter explores the behaviors of self propelled agents out of equilibrium, with active suspensions, such as swimming bacteria in solutions, serving as impactful…
