Research & Codes

Here we bring together in one place active research we are engaged in. Much of this takes the form of computational essays which, in our case, are in Python-based Jupyter notebooks and interactive JavaScript based Observable notebooks. 

We’ve organised our work in a mind map below to make it convenient to navigate through various concepts. We’ve also written research posts to provide a more chronological view of our work - these include a concise overview of a concept and a reference to the corresponding notebook.

We are building a community so we’d love you to get involved. You can of course contact us directly - we are very friendly ? .

In this third tutorial of the series on quantum particles in “boxes”, we show how the rate of quantum tunnelling of a particle through a barrier can be enhanced by placing identical boxes next to each other. Instead of the slow exponential decay that we found in the last tutorial, we find that the probability to find the particle in either box rapidly oscillates.

This notebook is the third tutorial in a series that explores the dynamics of quantum particles in a box

In this second tutorial of the the series on quantum particles in “boxes”, we try to confine a stationary particle inside a square potential well only to find it gets out. The wave nature of quantum particles produces reflection and transmission behaviour that we are more familiar with in the world of classical waves.

We begin this tutorial series on quantum particles in “boxes” by building the computational tools needed to explore the motion of particles in various confining potentials.  We need to do this because we are using Observable inside the browser to make things interactive - there are no quantum libraries for the browser like there are for Python (see QuTiP).
