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 Yambo PostProcessing(YPP)
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.
Psi-k highlight. Non-linear response of solids and nanostructures: a real-time prospective
In recent years many theoretical approaches and computational codes have been developed to study optical response of bulk materials, ranging from many-body perturbation theory to density functional like methods. However the major part of these approaches are limited to the linear optical regime. The few that are formulated in real-time are based on time-dependent density […]
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.

The Yambo YouTube channel is finally online!On our channel you can find all lectures and tutorials given at the Yambo Virtual School plus other interesting talks given by the YAMBO developers.The videos include also interesting references to learn many-body physics and optical properties. Hereafter the list of available lectures: Session on nonlinear opticsYambo parallelism and HPCElectron-phonon coupling […]
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 […]
New tutorial on electron-phonon coupling
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 […]
