Briefings

Researchers from Science Tokyo used superconducting vortices to prove clogging is a phase transition, not just pinning. They applied a two-step measurement protocol to distinguish the two phenomena and identified a shared critical point, enabling better prediction and control of clogging in various systems.

Key points

• Scientists from Science Tokyo utilized superconducting vortices to experimentally prove that clogging is a phase transition rather than conventional pinning.
• A two-step measurement protocol was employed to distinguish clogging from pinning, revealing both transitions share a critical point.

Context

This research addresses a long-standing experimental gap in understanding clogging mechanisms, providing a theoretical framework for predicting and controlling flow blockages in diverse systems.

Limitations

The study relies on a specific two-step measurement protocol; results may not apply universally to all clogging scenarios without further validation across different systems.
