From the above solution of the Schrödinger equation, we know the outgoing wave is a spherical one, so in a particular direction the amplitude decreases.

But that doesn’t happen with a plane wave. The clearest way to handle this is to put the system in a big box, a cube of side \(L\), with periodic boundary conditions. is a solution of the Schrodinger equation, the function a (where a is a constant) is also a solution. The multiplicative factor a therefore has to be chosen such that the function a satisfies (3).

This process is called normalizing the wavefunction. In general, there will be solutions to the Schrodinger equation (1) whose integral is infinite. Hence, a single Taylor series representation of a function can span the entire range needed for a corresponding independent variable.

We decided to find eigenvalues to 14 decimal digits by solving one-dimensional Schrödinger equations by the "shooting method" by employing a single Talylor series in each case. A stable and convergent second-order fully discrete finite difference scheme with efficient approximation of the exact absorbing boundary conditions is proposed to solve the Cauchy problem of the one-dimensional Schrödinger equation.

The Time Independent Schrödinger Equation Second order differential equations, like the Schrödinger Equation, can be solved by separation of variables.

These separated solutions can then be used to solve the problem in general. Assume that we can factorize the solution between time and space. In quantum physics, you can break the three-dimensional Schrödinger equation into three one-dimensional Schrödinger equations to make it easier to solve 3D problems.

In one dimension, the time-dependent Schrödinger equation (which lets you find a wave function) looks like this: And you can generalize that into three dimensions like this: Using the Laplacian operator, you [ ].

It is worth mentioning that the numerical solution of the Schrödinger equation in undergraduate courses was discussed by several authors in the past [2–9] and recently we have resorted to one of the available shooting methods for the discussion of the Wronskians that enable us to take into account the asymptotic behaviour of the Author: Francisco M Fernández.
