Visual Quantum Mechanics





Thomas Lang: Mach Zehnder Interferometer

A one-dimensional model showing a particle in a box with reflecting boundary conditions and a delta-function barrier in the middle.




Erek Bilgici: Bound States in a Pöschl-Teller Potential Well

The Pöschl-Teller potential is a smooth potential well of the form V(x) = 1/cosh(x)2. Here you can see an animation of a superposition of bound states that performs a periodic motion and a parameter animation of the bound states (depending on the depth or width of the potential).



Julian Grond and David Kammerlander: Bohmian Particles in One Dimension

Bohmian mechanics is a hidden variable theory of quantum mechanics. Here are some visualizations of Bohmian particles in one space-dimension: Particles at a rectangular potential step, a smooth step, and a rectangular barrier.
