I identified the plastic deformation units, called Anankeons, in metallic glasses using a molecular dynamics-based method called "frozen atom analysis." This technique detects the atoms responsible for deformation by observing changes in the system’s cooperative motion. As a result, I revealed that cooperative groups of approximately 40 atoms, indistinguishable by conventional structural indicators, act as the deformation units.
