QUESTION

solving 1D Schrödinger equation with Numerov method (python)

Asked 2017-Nov-24 at 04:43

Good evening.

I'm currently trying to solve the 1D Schrödinger eq. (time independent) with the Numerov method. The derivation of the method is clear to me but I have some problems with the implementation. I tried to look for solutions on google, and there are some (like this one or this one), but I don't really understand what they are doing in their codes...

The Problem:

With some math you can get the equation to this form: where . For the beginning I'd like to look at the potential V(x)=1 if -a.

Since I don't have values for the energy or the first values of Psi (which are needed to start the algorithm) I just guessed some...

The code looks like this:

Unfortunately I don't quite remember the quantum physics so I don't understand some details. Still I see some bugs in your code:

Why inside numerov_step you square k1, k2 and k3?

Install Numerov

You can download it from GitHub.
You can use Numerov like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
