Exact Solutions of the two-dimensional Schrödinger equation with certain central potentials

Abstract

By applying an ansatz to the eigenfunction, an exact closed form solution of the Schrödinger equation in 2D is obtained with the potentials, $V(r)=a{r}^2+b{r}^4+c{r}^6$, $V(r)=ar+b{r}^2+c{r}^{-1}$ and $V(r)=a{r}^2+b{r}^{-2}+c{r}^{-4}+d{r}^{-6}$, respectively. The restrictions on the parameters of the given potential and the angular momentum $m$ are obtained.
