Emergence of rotating clusters in active Brownian particles with visual perception

Area of Science:

• Complex Systems
• Statistical Physics
• Active Matter Physics

Background:

• Active particles, self-propelled entities, exhibit complex collective behaviors.
• Understanding group formation and dynamics is crucial for active matter systems.
• Visual perception can influence particle interactions and emergent structures.

Purpose of the Study:

• To investigate the group formation and dynamics of active particles with visual perception.
• To analyze the correlation between persistent motion and emergent structures.
• To characterize the behavior of rotating clusters formed by these particles.

Main Methods:

• Utilized Langevin dynamics simulations to model particle behavior.
• Incorporated orientational responses based on nearest neighbor positions within a vision cone.
• Analyzed persistence probability and orientational correlation functions.

Main Results:

• Observed the emergence of rotating clusters when visual perception range is intermediate.
• Found a strong correlation between persistent motion and emergent structures.
• Rotating clusters exhibited rapidly decaying persistence probability and oscillatory orientational correlations.

Conclusions:

• Visual perception in active particles can lead to the formation of dynamic rotating clusters.
• The interplay between particle persistence and visual cues dictates emergent collective behavior.
• The observed dynamics provide insights into self-organization mechanisms in active matter.
