Abstract

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.
