Hereafter we present tutorials on real-time spectroscopy and non-linear optics. Notice that the first tutorial on "Linear response" is preparatory for all the others.

Linear response

in real-time

Linear response in real-time.
In this tutorial you will learn how to perform real-time simulation to get the dielectric constant of bulk materials. Results will be compared with standard linear response theory.


in AlAs

Second Harmonic Generation (SHG) in AlAs
In this tutorial we will calculate second harmonic generation (SHG) in AlAs


and SHG

Correlation effects in SHG
In this tutorial we will introduce correlation effects in the SHG spectra. Different approaches will be considered.


in Silicon

Third Harmonic Generation (THG) in Silicon.
In this tutorial we will calculate the THG response of bulk silicon.



Real-time BSE.
This tutorial explains how to run a real-time Bethe-Salpeter calculation.

Dealing with large


Dealing with large systems.
This tutorial explains how Lumen is parallelized and how you can calculate non-linear response in complex and large systems.

Spin -- orbit coupling

Spin-orbit coupling.
How to include spin-orbit coupling in calculations.
