Sn. Taraskin et al., Propagation of vibrational excitations in disordered atomic structures by a normal-mode analysis, COMP PHYS C, 122, 1999, pp. 540-541
A new method based on a normal-mode analysis is proposed for the investigat
ion of the propagation of plane-wave vibrational excitations in disordered
atomic structures. Analysis of the spectral densities in k-space is a key p
oint of the current approach. (C) 1999 Elsevier Science B.V. All rights res
