Supplementary Material for "Interactive Sonification of 2D Quantum Systems"

This paper presents novel sonification methods for the auditory representation of 2D quantum systems and their temporal evolution, encompassing examples such as the tunnel effect, single and double slit interference or behavior of light or matter in a given potential function. The simulation involves numeric integration of the Schrödinger equation. The sonification is based on three paradigms: (a) scanning the probability amplitude along a 1D-manifold (i.e.~curve) as a waveform, (b) probing the probability amplitude as spectral activation along a 1D-manifold, (c) traversing the full 2D field as an audification. We illustrate the methods with sonification examples, discuss what can be learned about the behavior of quantum systems in non-stationary transitions and propose application scenarios in physical, musical and educational contexts.
