Abstract

The Bound States Calculation Lab determines the bound states and the corresponding wavefunctions in a square, harmonic, triangular and v-shaped potential well. Maximum number of eigenstates that can be calculated is 20. For better understanding the physics behind the bound-state calculation lab that numerically solves for the eigenstates and the eigenfunctions using the shooting methods, we have also provided the following reading material:

Tutorial on Bound States Calculation

Solution of the Harmonic Oscillator Problem

Also, we have prepared a number of exercises that demonstrate the full potential of this tool and also motivate the students to develop analytical skills to solving this type of problems:

Exercise: Bound States Calculation

Exercise: Brute-Force Approach Applied to Harmonic Oscillator Problem and Coulomb Potential in 1D

Exercise: Operator Approach to Harmonic Oscillator Problem

Upgrades from previous versions: Version 1.0.1: Fixed a bug which crashed the code for larger parabolic confinements. This was a bug identified by a user and posted as a question.
