abstract

We study and generalize the momentum operator satisfying the extended uncertainty principle relation (EUP). This generalized extended momentum operator (GEMO) consists of an arbitrary auxiliary function of position operator, $\mu \left( x\right) $, in such a combination that not only GEMO satisfies the EUP relation but also it is Hermitian. Next, we apply the GEMO to construct the generalized one-dimensional Schr\"{o}dinger equation. Upon using the so called point canonical transformation (PCT), we transform the generalized Schr\"{o}dinger equation from $x$-space to $z$-space where in terms of the transformed coordinate, $z$, it is of the standard form of the Schr\"{o}dinger equation. In continuation, we study two illustrative examples and solve the corresponding equations analytically to find the energy spectrum.
