Interplay of activity and interfacial tension in multi-species systems

Characterize the interplay between activity-driven stresses and interfacial tension in multi-species systems composed of interacting motile and non-motile phases.

Background

A growing body of work has examined active nematic behavior, defect-mediated phenomena, and phase separation, but the combined influence of activity and interfacial tension in systems containing both motile and non-motile components is insufficiently understood.

By constructing a biphasic nematic model and exploring parameter dependencies, the study begins to map how activity and interfacial tension jointly affect defect transport and charge segregation, while highlighting that this broader interplay remains largely unexplored.
