Nieto Física, Astronomía y Matemáticas mass jumps Delta interactions periodic potentials energy band structures We discuss some of the properties of the spectrum of a Dirac comb with periodic mass discontinuity. Based on the relationship between the two different masses, we derive the general behavior of the spectra for both cases E > 0 and E < 0. The relationship with the constant mass model for the Dirac comb and the generalization to periodic quantum chains with n different masses are also discussed. 2013 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57028306015 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
