How to analyse excitons

In this tutorial you will learn (for a 2D-hBN) how to:

• How to analyze a BSE optical spectrum in terms of excitonic eigenvectors and eigenvalues
• How to plot the excitonic wavefunction

Prerequisites

Previous modules

• You must have completed the tutorial on 2D hBN.
• You must have completed the tutorial on 2D hBN.

You will need:

• ypp executable
• xcrysden executable
• gnuplot or xmgrace executable

YAMBO calculations

If you have completed the tutorial you should have all the databases required to do this tutorial in your SAVE and 2D directories

$ ls 

If not unpack the tarfile and use those directories

$ tar -xcvf hBN-2D.tar
$ cd YAMBO_TUTORIALS/hBN-2D/YAMBO
$ ls
