Active Matter & Non-Equilibrium Systems

This research group investigates the computational modeling of active matter—systems composed of self-propelled particles that consume energy to generate motion and exhibit collective behaviors far from thermodynamic equilibrium. Our primary focus is developing and implementing novel simulation algorithms within the LAMMPS molecular dynamics framework to capture the rich phenomenology of active systems, including motility-induced phase separation, flocking transitions, and emergent pattern formation.

We explore both biological active matter (bacterial suspensions, cellular monolayers, cytoskeletal networks) and synthetic analogues (self-propelled colloids, active granular systems) through coarse-grained computational models. Our methodological contributions include custom pair styles and fix commands for LAMMPS that encode active forces, torques, and alignment interactions. This work advances fundamental understanding of non-equilibrium statistical mechanics while opening pathways toward designing programmable active materials with applications in soft robotics, targeted drug delivery, and self-healing materials.
