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…
Statistical Language Competition Model with Dynamic Edge Weighting on a Random Network
Somyaranjan Chakra, Mohit Anand Madhesia, Shradha Mishra
This paper presents a computational study of language competition dynamics on Erdős--Rényi random networks, extending the foundational Abrams--Strogatz model through two novel cont…
Shape Evolution and Dynamics of Deformable Ring
Arun Kumar, Partha Sarathi Mondal, Pritha Dolai +1
We numerically investigate the dynamics of a deformable closed ring filled with active particles. The ring is modeled as a flexible boundary made up of passive beads interacting wi…
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…
Phase separation kinetics of 2-TIPS at low density: Cluster growth by ballistic agglomeration
Nayana Venkatareddy, Partha Sarathi Mondal, Shradha Mishra +1
We study the kinetics of two-temperature induced phase separation (2-TIPS) in dilute binary mixtures of active ("hot") and passive ("cold") particles using molecular dynamics simul…
Spatiotemporal Chaos and Defect Proliferation in Polar-Apolar Active Mixture
Partha Sarathi Mondal, Tamas Vicsek, Shradha Mishra
Chaotic transitions in inertial fluids typically proceed through a direct energy cascade from large to small scales. In contrast, active systems, composed of self propelled units,…
Growth Laws and Universality in 2-TIPS: Microscopic and Coarse grained approach
Nayana Venkatareddy, Partha Sarathi Mondal, Jaydeep Mandal +2
Two temperature induced phase separation(2-TIPS) is a phenomenon observed in mixtures of active and passive particles modeled by scalar activity where the temperature of the partic…
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…
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…
Dynamics of phagocytosis through interplay of forces
Partha Sarathi Mondal, Pawan Kumar Mishra, Mitali Thorat +2
Phagocytosis is the process by which cells, which are 5 to 10 times larger than the particle size, engulf particles, holding substantial importance in various biological contexts r…
Dynamical Swirl Structures Powered by Microswimmers in Active Nematics
Partha Sarathi Mondal, Pawan Kumar Mishra, Tamás Vicsek +1
Active nematics, in their pure form, have demonstrated a plethora of dynamic and steady state behaviors, including large-scale dynamic structures, collective flows, and intricate m…
Directional cues affect the collective behaviour of Self propelled particles in one dimension
Pawan Kumar Mishra, Abhra Puitandy, Shradha Mishra
This study explores the effect of quenched disorder on the characteristic of self-propelled particles in one-dimension. Here,particles interact with disorder which serve as directi…
