contents Vibrations in one-dimensional hybrid Fibonacci/periodic structures A. Montalbán V.R. Velasco J. Tutor F.J. Fernández-Velicia Física, Astronomía y Matemáticas quasi phonons Multilayer systems periodic structures We have studied the vibrational frequencies and atom displacements of one-dimensional systems formed by combinations of Fibonacci quasi-periodic stackings with periodic ones. The materials are described by nearest-neighbor force constants and the corresponding atom masses.These systems exhibit differences in the frequency spectrum as compared to the original simple Fibonacci generations. The most importantfeature is the presence of separate confinement of the atom displacements in one of the sequences forming the total composite structure fordifferent frequency ranges. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57036163003 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
