This figure shows the local density of state of a quantum billiard with a stadium shape.
The entire code to perform this calculation (including making the figure) is reproduced below and is, as one can see, rather small.
Transport properties of a Corbino disk across a quantum Hall transition. Left
panel: winding number of the reflection matrix, which has to change from 0 to 1
across the transition. Right panel: conductance across the transition, showing
quantized conductance peaks.

* A piece of bilayer graphene lattice.
* A quantum wire (gray) attached to a superconducting electrode (blue) give rise to a Majorana bound states
which can be seen in the spectrum of the device (upper and lower right).
In this example, one can see a quantum wire (gray) to which is attached a superconducting electrode (blue).
This device has been built in order to give rise to a Majorana bound states close to the superconducting-normal interface.
The latter can be seen in the spectrum of the device (REF).

"numerical experiments" can not only be used to interpret the experimental data but also as an aid in designing the sample geometry or in the choice of
materials.
