Before proceeding with the real-time simulations it is useful to compute the Independent Particles (IP) absorpti The resulting spectrum will give an idea of the energy involved in the real-time simulations

This tutorial will show how to perform a real-time calculation with Yambo on hBN monolayer. We will go through different appro Let us start by going to the previous folder where we ran the real-time initialization and the tutorial on linear response:

...to the final TPA spectrum. For the calculation of the TPA we will use the real-time approach proposed in Ref. <ref name=nl>[https://arxiv.org/abs/1309.4012 Non for more detail see Ref.<ref name=tpa></ref>.
