Modern 2:Square Well Potentials

• This applet explores energy levels, bound states, boundary conditions and lots more. Run it until you understand it. square well java applet

• Here is the math behind the easiest case. An infinite square well. I will do this in detail in class. the finite square well (pdf file).

Also, at this point it is useful to compare the QM results with what you would get with the closest classical analogy, a string with clamped ends.

• A simple mathematica notebook showing the eigenstates and their time dependence

• Here is the math behind the finite square well. I wil cover most of this

in class. finite square well math

• Here is an animation of a gaussian wavepacket in an infinite square well wavepacket animation
