Generalized Extended Momentum Operator

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.
