Dirac comb with a periodic mass jump
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 Di...

| description | 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. |
