Section 8.2: The Quantum-mechanical Free-particle Solution
Please wait for the animation to completely load.
In order to tackle the free-particle problem, we begin with the Schrödinger equation in one dimension with V(x) = 0,

1d044d43619b496e | There are plenty of free particles — particles outside any square well —in the universe, and quantum physics has something to say about them. The discussion starts with the Schrödinger equation:
Say you’re dealing with a free particle whose general potential, V(x) = 0. In that case, you’d have the following equation:... |

I'm using the Crank-Nicholson method to solve the time-dependent Schrödinger equation with the split-operator method. I'm getting some weird results that are probably the result of a bug somewhere in my code.
Just in case, I thought I should probably check to see if the method I'm using is un... |
