Abstract: We consider the stationary one-dimensional Schrödinger equation with potential u(x; i) = 2 ∑ j=−2 fj(i)x , where the coefficients fj(i) are functions of a discrete parameter i. We establish the most general form of the coefficients fj(i) and obtain the ladder operators for the solution of Schrödinger equation by a Darboux transform. Generally speaking, the Darboux transform is obtained through a so-called superpotential W (x), which is derived from a Riccati equation. We first propose… CONTINUE READING
