Quantum Materials
Researchers at KAIST have directly observed how charge density waves form uneven, patchy patterns inside a quantum material during a phase transition. Using advanced 4D-STEM microscopy, the team mapped the strength and coherence of these electron patterns at nanoscale resolution. The findings reveal that electronic order persists in small pockets even above the transition temperature.

Researchers have experimentally observed a hidden quantum geometry in materials that steers electrons similarly to how gravity bends light. The discovery, made at the interface of two oxide materials, could advance quantum electronics and superconductivity. Published in Science, the findings highlight a long-theorized effect now confirmed in reality.
