Exact solutions for the inverse problem of the time-independent Schrödinger equation

Abstract

We introduce an “inverse method” for solving the time-independent Schrödinger equation. Rather than derive wave functions that are solutions for a given external potential V(r→), we ask the inverse question of which V(r→) will have a given probability density function P(r→). Several examples of ground states in one, two, and three dimensions are presented for both well-known and more exotic probability density functions in position space.
