Data Driven Equation Discovery for Phase-Ordering Dynamics : From Allen Cahn to the Ising Model
Partha Sarathi Mondal, Manav Kumar Jalan, Anish Kumar +1
Data-driven discovery of governing equations from spatiotemporal data offers a promising route to obtaining coarse-grained descriptions of complex dynamical systems. Here, we inves…
Density-Induced Reentrant Coarsening in a Two-Temperature System
Partha Sarathi Mondal, Anish Kumar, Nayana Venkatareddy +2
Understanding how nonequilibrium driving modifies phase-separation kinetics remains a fundamental challenge. Here we show that phase separation in a two-temperature system exhibits…
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…
From LRO to Disorder via QLRO in Spatially Inhomogeneous Polar Flock
Anish Kumar, Vivek Semwal, Shradha Mishra
We study the collective behavior of a polar flock in an inhomogeneous environment in two-dimensions. The inhomogeneity is modelled by introducing regions at random locations on the…
Adaptive dynamics of Ising spins in one dimension leveraging Reinforcement Learning
Anish Kumar, Pawan Kumar Mishra, Riya Singh +2
A one-dimensional flocking model using active Ising spins is studied, where the system evolves through the reinforcement learning approach \textit{via} defining state, action, and…
Synchronous and Asynchronous Updates of Active Ising Spins in One Dimension
Anish Kumar, Sudipta Pattanayak, R. K. Singh +1
How do update rules affect the dynamical and steady state properties of a flock? In this study, we have explored the active Ising spins (s = +-1) in one dimension, where spin updat…
Dynamics of active run and tumble and passive particles in binary mixture
Vivek Semwal, Jay Prakash, Shradha Mishra
We study a binary mixture of disk-shaped {\it active run and tumble } particles () and passive particles on a two-dimensional substrate. Both types of particles are atherm…
