'Singing' electrons synchronize in Kagome crystals, revealing geometry-driven quantum coherence

Physicists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a striking new form of quantum behavior. In star-shaped Kagome crystals-named after a traditional Japanese bamboo-basket woven pattern-electrons that usually act like a noisy crowd suddenly synchronize, forming a collective "song" that evolves with the crystal's shape. The study, published in Nature, reveals that geometry itself can tune quantum coherence, opening new pos...
