This Tutorial: what will you learn

You will learn how to set up and run calculations to get optical absorption spectrum by using the Bethe-Salpeter equation starting from a previously calculated electronic structure. In addition you will learn to use post-processing tools to analyze the excitons and special numerical treatment needed for low dimensional materials.

Before starting: what do you need

- If you are not familiar with the Bethe-Salpeter equation and/or optical response in periodic systems, you are encouraged to ADD BACKGROUND MATERIAL LINKS

- We suppose you know already how to generate the Yambo databases and familiar with the input, output and command line interface‎‎.

- In the Bethe-Salpeter equation the quasiparticle energies are used, we then recommend to complete the GW tutorial even though not strictly needed.

Tutorial modules:

This tutorial consists in four parts:

On bulk h-BN:

On 2D h-BN monolayer:
