Darboux transformations and hidden quadratic supersymmetry of the one-dimensional stationary Dirac equation

N. Debergh, A. A. Pecheritsin, B. F. Samsonov +1

A matricial Darboux operator intertwining two one-dimensional stationary Dirac Hamiltonians is constructed. This operator is such that the potential of the second Dirac Hamiltonian…
