Fermi Golden Rule Simulator - Picture book

This simulates a discrete level embeded in a (quasi) continuum:

This is TDSE:

And this is the expansion of the wavefunction:

The Hamiltonian of the model is shown here:

Before the decay starts, the situation is:

During the decay:

the thick lines represent the occupation probabilities, obtained by the integration of the Time-Dependent Schroedinger Equation

And this is our representation in the program:

In fact, it looks more like this:
