Visualizing the impact of quenched disorder on 2D electron Wigner solids

Researchers developed a new technique combining atomically resolved scanning tunneling microscopy with neural-quantum-state quantum Monte Carlo simulations to visualize the impact of quenched disorder on 2D electron Wigner solids. This method, published online in Nature on June 17, 2026, establishes a powerful framework for clearly identifying two distinct defect-induced disorder regimes. The study's findings enable a deeper understanding of how imperfections in the material structure affect the behavior of electrons in a Wigner solid state. This advancement is crucial for fields investigating quantum materials and their potential applications in future electronic devices. The combined approach allows for unprecedented detail in observing and analyzing the complex interactions within these quantum systems.
