Step into the quantum dance floor of 2D materials as we explore the groundbreaking discovery of moiré phasons—a new class of ultrasoft vibrational modes revealed in twisted bilayer WSe₂. Using ultrahigh-resolution electron ptychography, researchers have, for the first time, directly imaged atomic-scale thermal vibrations and confirmed long-standing predictions about these exotic moiré modes. From soliton hotspots to AA-stacked rhythms, discover how this study opens an exciting new window into the thermal behavior of layered materials and what it means for future quantum devices.
