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 will need:

  • ypp executable
  • xcrysden executable
  • gnuplot or xmgrace executable
