A mechanical model of tunnelling
Amaury Mouchet
It is shown how the model which was introduced by Mouchet (2008 Eur. J. Phys. 29 1033) allows one to mimic the quantum tunnelling between two symmetric one-dimensional wells.

Finding gaps in a spectrum
Hector Giacomini, Amaury Mouchet
We propose a method for finding gaps in the spectrum of a differential operator. When applied to the one-dimensional Hamiltonian of the quartic oscillator, a simple algebraic algor…
