Electron ordering mapped in quantum material with cryogenic 4D-STEM

Tokyo, Japan (SPX) Jan 20, 2026
Electronic order in quantum materials often arises through intricate, non-uniform patterns that shift across space. A well-known example is the charge density wave (CDW), an ordered electronic state that forms periodic patterns at low temperatures. Although CDWs have been studied for decades, directly observing how their strength and spatial coherence evolve through a phase transition has remain
