Robust Discovery of Coarse-Grained Continuum Equations from Microscopic Dynamics
Partha Sarathi Mondal, Manav Kumar Jalan, Anish Kumar +1
The discovery of governing partial differential equations (PDEs) directly from spatiotemporal data has emerged as a powerful tool for understanding the dynamics of complex systems.…
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…
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…
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…
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…
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…
