Exactly solvable pseudoscalar periodic Dirac potentials from Darboux transformations and underlying nonlinear supersymmetry.
This paper deals with the one-dimensional Dirac equation. Using Darboux transformation the authors construct new pseudoscalar periodic potentials. Moreover, they prove a theorem establishing the polynomial factorization of Dirac Hamiltonians by Darboux transformation operators.
