Research Projects

The kinetics of phase separation in multi-component immiscible fluid mixtures have been extensively studied from various perspectives, including physics, material science, and engineering. Computer simulations and experiments have predicted various regimes characterized by a time-dependent length scale for domain growth pattern or domain morphology. However, a richer physics is expected when the constituent component is complex or the mixture is confined in complex geometrical structure. For example, aspherical particles in a system can lead to distinct energy values depending on their relative orientation. Geometrical confinement of the binary solution inside a host structure can modify coarsening dynamics depending on the host structure and interactions among them. Segregating systems containing living particles that self-propel have the potential to exhibit richer phase behavior. The phase ordering process of these systems involves complex bicontinuous structure formation and is poorly understood. The aging dynamics of these non-equilibrium phenomena are unexplored, and incorporating complex nonlinear behavior into coarse-grained theoretical models remains challenging. The main research goal of this project is to investigate and understand the phase separation behavior of non-living and living systems using computer simulations. The study aims to study the non-equilibrium dynamics of these systems and their evolution to a new equilibrium state via domain formation and coarsening when quenched from a high-temperature homogeneous phase inside the miscibility gap.
