Vibrational spectra in glasses Grigera, T.S. Martín Mayor, Víctor Parisi, G. Verrocchio, P. The findings of X-ray and neutron scattering experiments on amorphous systems are interpreted within the framework of the theory of Euclidean random matrices. This allows to take into account the topological nature of the disorder, a key ingredient which strongly affects the vibrational spectra of those systems. We present a resummation scheme for a perturbative expansion in the inverse particle density, allowing an accurate analytical computation of the dynamical structure factor within the range of densities encountered in real systems. 2023-06-20T20:27:09Z 2023-06-20T20:27:09Z 2023-06-20T20:27:09Z 2002-04 journal article https://hdl.handle.net/20.500.14352/60296 0141-8637 10.1080/13642810110084588 eng AEN99-0990 AEN97-1693 open access Taylor & Francis
