Non-reciprocity drives a Brownian dimer out of equilibrium
Suman Pramanik, Soham Dutta, Arnab Saha
We consider the minimal model of a two dimensional Brownian dimer consisting of two overdamped monomers, trapped in an isotropic harmonic potential and mutually coupled by a non-re…
Brownian gyration of an inertial ellipsoid
Soham Dutta, Arnab Saha
Recent studies on Brownian gyration (BG) have focused primarily on spherically symmetric particles under overdamped conditions. To explore BG in the underdamped regime with a spher…
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…
Flow Of Information In a Mechanically Quenched Confined Flock
Md. Samsuzzaman, Mohammad Hasanuzzaman, Ahmed Sayeed +1
Living entities in a group communicate and transfer information to one another for a variety of reasons. It might be for foraging food, migration, or escaping threats and obstacles…
