In this tutorial you will learn how to calculate optical spectra using Yambo, starting from a DFT calculation and ending with a look at local field effects in the optical response.
We will use a 3D system (bulk hBN) and a 2D system (hBN sheet).
Before starting, you need to obtain the tarballs for hBN and hBN-2D. See instructions on the main tutorials page.
The steps are the following:
Step 1: DFT calculation of bulk hBN and conversion to Yambo
Follow the DFT and p2y module on bulk hBN and then return to this tutorial "First steps..."
There is no need to complete the module on 2D BN.
Step 2: Initialization of Yambo databases
Use the SAVE folders that are already provided, rather than any ones you may have generated previously.
Follow the module on Initialization, for both hBN and 2D-hBN, and return to this tutorial "First steps..."
Step 3: Yambo's command line interface
Yambo uses a command line interface to select tasks, generate input files, and control the runtime behaviour.
Starting from the hBN/YAMBO folder, follow the module on Input file generation and command line options and then return to this tutorial "First steps...".
Step 4: Optical absorption in hBN
Follow the module on Optics at the independent particle level for bulk hBN and return to this tutorial "First steps..."
Step 5: Optical absorption in 2D BN
It is now time to complete the module on 2D BN.
Follow the DFT and p2y module on 2D hBN, you can repeat all the steps you already did for hBN bulk and then return to this tutorial "First steps..."
Follow the module on Local fields for 2D BN.
