(color online) Correlation between local structures with more degree of LFFS and the irreversible atomic rearrangement during deformation. A slice in the middle of the samples along Z direction with a thickness of the first minimum of the pair correlation function is taken for the illustration. Black points represent the atoms having more degree of LFFS ( ) at the strain of 5% (a) and 10% (b). The red and blue areas are the mostly deformed regions emerged in the time interval of 40 ps and the less deformed regions, respectively (reproduced from ^[30]).
