A study is made of the alteration in energy spectra after g bosons are added to the interacting boson model, when the model is taken to the SU(3) limit. 相似文献

We extend the usual static view of short range order in metallic glasses to a dynamical model of local order. We use an atomistic simulation of a NiZr glass to investigate time-dependent fluctuations of the atomic environment. We show that, even in the "frozen" glass, the solute-centered clusters change their identities between distinct polyhedron types. The frequency spectrum of these transitions exhibits a characteristic peak which we show to be related to a universal vibrational anomaly of disordered solids: the controversial boson peak. 相似文献
