Abstract
Glasses, in general, and metallic glasses (MG), in particular, show an excess of vibrational modes above the Debye level, in what is commonly termed as Boson Peak (BP). Structural and elastic heterogeneities at the nm scale is an intrinsic feature of glasses. These heterogeneities determine the physical properties in the nm-scale region, this is the transition region between the atomic level, defined by the particular atomic bonding and packing of the substance, and the macroscopic elastic conti...
