This intriguing analysis observes Active Brownian Particles (ABPs) that interact through a double repulsive length scale potential. The research uncovers the conditions leading to complex structures within dense phases and anomalous dynamics not previously documented in active particles.

Observations:

• Identification of two distinct interaction regimes based on the strength-to-activity ratio.
• Formation of unique structures during the phase separation process.
• Anomaly in the representation of particle dynamics.

Broader implications:

• Provide a benchmark for developing materials with custom phase behaviours.
• Contributes to the understanding of active matter and its potential applications.

In my perspective, the findings present a milestone for active particles, indicating the possibility of customizing behaviours for various industrial uses. The comprehensive characterization of such particles opens avenues for materials science, leading to potentially groundbreaking technologies.
