Here we have the animation files (movies) for the APHY439 course. They show the time evolution of wave functions in one dimensions for a few simple cases. The actual matlab code I used to generate the movie frames are also provided and the end for your perusal and/or experimentation (the “.m” files).

Particle in a box (infinite square well)

Gaussian centered mid box with zero average momentum 

Gaussian centered mid box with mean positive momentum 

Square wave function centered mid box with zero mean momentum 

An infinite well problem where the initial starting point is an eigenstate, here the n=2 state of the well. The time evolution is quite dull — this is meant to illustrate how eigenstate show no real time evolution. 

An infinite well problem where the initial starting point is the n=2 eigenstate cut off in the left half (i.e., not an eigenstate in fact). Show actual time evolution compared to the case above! 
Quantum Harmonic oscillator

Gaussian centered at x=0 with positive average momentum 

Groundstate wave function translated to xi=7, i.e. a coherent state 
Free particle

Gaussian centered at x=0, no momentum 

Gaussian centered at x=0, positive momentum 

Square wave initial function centered at x=0, no momentum 

Square wave function centered at x=0, positive momentum 
Potential scattering
The potential well is square, extends from a/2 to a/2 and has total area alpha under it (i.e. its value is alpha/a).

Potential well with a single bound state and incoming low energy packet: a=0.5, alpha=2, Gaussian packet sigma=10 

Single bound state, medium energy packet: alpha=2, a=0.5, sigma=4 

Single bound state, medium energy packet but narrower packet: alpha=2, a=0.5, sigma=2 

Potential with bound state, packet with wide energy spread: sigma=1, alpha=2, a=0.5, initial momentum k0=1 

Potential with multiple bound states with low energy packet incoming: sigma=10, alpha=11, a=10 (this is a wide potential well).
