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.yambocode.eu/wiki/index.php/Third_Harmonic_Generation_(THG) We explain how to obtain xhi^3(\omega) from realtime simulations and how to analyze the results, also using YamboPY postprocessing 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 dephasing or radiative lifetime effects. This kind of calculations can be useful to estimated excitonexciton transitions and they can be compared with transient absorption/transmission. Here the tutorial: Pump and Probeand…

New tutorial on phononassisted luminescence by finite atomic displacements
A new tutorial on phononassisted luminescence by finite atomic displacement is available in the wiki webpage. In this tutorial we explain stepbystep 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 Yambo PostProcessing(YPP)
A new tutorial on Yambo PostProcessing(YPP) is available online.All possible postprocessing tools are presented with relative link to the tutorials when available. Notice that an alternative postprocessing tool in python with additional features is available here: yambopy.

New tutorial on parallelization of nonlinear optics calculations
A new tutorial on parallelization of the nonlinear 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 webpage 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 selfconsistent GW on eigenvalues only
A new tutorial is available in the Yambo wiki on selfconsistent GW on eigenvalues only (evGW). In this tutorial we illustrate how to use Yambo to perform selfconsistent GW calculations in G and W. Selfconsistent GW on eigenvalues only is a good approximation when DFT wavefunctions are not so different from GW ones, for example materials…

New tutorial on electronphonon coupling
A new tutorial is available in the Yambo wiki on electronphonon interaction. This tutorial starts from the calculation of electronphonon 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…
