Emergence of Dynamical Anisotropy induced by Demixing in a Binary System with Differential Diffusivity under an External Potential
Rashmi Trivedi, Subhajit Paul, Sumanta Kundu +1
Spontaneous demixing in active matter is a ubiquitous phenomenon that is crucial for numerous living processes ranging from bacterial swarming to sorting of cells in dense tissues.…
From Global Flocking to Local Clustering: Interplay between Velocity Alignment and Visual Perception of Active Particles
Mohit Gaur, Arnab Saha, Subhajit Paul
Collective behavior in biological systems was first captured by the Vicsek model, in which particles align their velocities in the average direction of neighbors, leading to cohere…
Interplay of activity and non-reciprocity in tracer dynamics: From non-equilibrium fluctuation-dissipation to giant diffusion
Subhajit Paul, Debasish Chaudhuri
Non-reciprocal interactions play a key role in shaping transport in active and passive systems, giving rise to striking nonequilibrium behavior. Here, we study the dynamics of a tr…
Crossover dynamics and non-Gaussian fluctuations in inertial active chains
Manish Patel, Subhajit Paul, Debasish Chaudhuri
We study the dynamics of inertial active particles in a one-dimensional chain with harmonic nearest-neighbor interactions, highlighting the interplay of persistence, interaction, a…
