Ep 13-Moiré Magic: Unveiling Atomic Vibrations in Twisted 2D Worlds

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.
