a, Local Voronoi area. b, Local chemical composition. c, Local potential energy. d, Local simple shear modulus. e, Local pure shear modulus. f, Spatial correlation of the non-affine displacement fields excited by quasi-static athermal deformation in the form of uniaxial tension (γxx) and simple shear (γxy) at very small strain. g, Transverse component of the lowest non-zero frequency vibrational mode, which shows quasi-localised modes (QLMs) with four-leaf pattern. h, Non-affine displacement field induced by uniaxial tension along the horizontal axis (strain: 4 × 10−5). The major QLM in the right top corner is not excited. i, Non-affine displacement field induced by simple shear along the horizontal axis (strain: 3 × 10−5). The major QLM is excited in this case. The vector amplitudes have been adjusted for better visualisation. These results are obtained for the glassy state shown in Fig. 6 in the main text.
