New tutorial on two-photon absorption
A new tutorial is present in the wiki web-page on the two-photon absorption (TPA). In this tutorial we show how to calculate TPA in bulk silicon using real-time dynamics. More details can be found here: https://www.yambo-code.eu/wiki/index.php/Two-photon_absorption

New tutorial on third harmonic generation (THG)
A new tutorial on the calculation of Third Harmonic Generation (THG) is available in the wiki webpage:https://www.yambo-code.eu/wiki/index.php/Third_Harmonic_Generation_(THG) We explain how to obtain xhi^3(\omega) from real-time simulations and how to analyze the results, also using YamboPY post-processing tool.

New tutorial on pump and probe spectroscopy
A new tutorial with yambo_nl on pump and probe spectroscopy is available on the wiki: Pump & Probe . This tutorial explains how to calculate pump&probe response without de-phasing or radiative lifetime effects. This kind of calculations can be useful to estimated exciton-exciton transitions and they can be compared with transient absorption/transmission. Here the tutorial: Pump and Probeand…

New tutorial on phonon-assisted luminescence by finite atomic displacements
A new tutorial on phonon-assisted luminescence by finite atomic displacement is available in the wiki web-page. In this tutorial we explain step-by-step how to calculate the luminescence spectra taking into account phonon vibration. The present approach can applied to indirect and direct band gap semiconductors where coupling with phonons play an important role. An example…

New tutorial on parallelization of non-linear optics calculations
A new tutorial on parallelization of the non-linear response is available here. We explain the different level of available parallelization and how to run calculations that require large memory.

New tutorial on optical properties at finite temperature
A new tutorial on optical properties at finite temperature is available in the wiki web-page of Yambo.Notice that in the present implementation in Yambo different approximation are done that could givenot perfect results, please read the carefully the tutorial.

New tutorial on self-consistent GW on eigenvalues only
A new tutorial is available in the Yambo wiki on self-consistent GW on eigenvalues only (evGW). In this tutorial we illustrate how to use Yambo to perform self-consistent GW calculations in G and W. Self-consistent GW on eigenvalues only is a good approximation when DFT wave-functions are not so different from GW ones, for example materials…
