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.

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…

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…

A new tutorial on Yambo PostProcessing(YPP) is available online.All possible post-processing tools are presented with relative link to the tutorials when available. Notice that an alternative post-processing tool in python with additional features is available here: yambopy.

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.

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.

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…

A new tutorial is available in the Yambo wiki on electron-phonon interaction. This tutorial starts from the calculation of electron-phonon matrix elements with Quantum Espresso and how to read them with Yambo. Then we explain how to calculated the effect of lattice vibration on the single particle levels, and how to use this correction to…
