This year, I’ve spent a lot of time diving into the world of two state quantum systems as a model to help understand nuclear reactions in sold state, in particular those reported in cold fusion (LENR) experiments.

As we described last time, this is not the typical way to view nuclear reactions. It’s more common to think about them as a quantum tunnelling problem as originally set out by Gamow ^{1}.

In order to make the connection between these two ways of viewing nuclear reactions, I’m creating another set of computational tutorials to complement the ones being made over at the two-state-systems repo.

This collection of tutorials is dedicated to exploring the quantum behaviour of particles moving under the influence of a confining potential - aka a “quantum box”. Such “boxes” can be square e.g. the infinite and finite square wells, or curved e.g. the harmonic potential. We’ll explore a variety of different kinds of boxes π¦ and how easily particles can escape from them.

The tutorials are fully interactive Observable notebooks. This means you can play with the simulations live in the browser without needing to install anything π₯³.

Enjoy.
