<p>New page for 2023 school (necessary because the title of the old page explicitly mentioned the 2021 school)</p> <p><b>New page</b></p><div>We are going to compute optical absorption spectra when strong excitonic effects are present via the Bethe-Salpeter equation.<br /> <br /> We will use bulk hBN as an example system. Before starting, you need to obtain the appropriate tarball: [https://www.yambo-code.org/educational/tutorials/files/hBN.tar.gz hBN.tar.gz]. For the last part of the convergence tutorial (step 4.), you will also need the [https://www.yambo-code.org/educational/tutorials/files/hBN-convergence-kpoints.tar.gz hBN-convergence-kpoints.tar.gz] tarball. See instructions on the [[Tutorials|main tutorials page]]. &lt;br&gt;<br /> We strongly recommend that you first complete the [[First steps: a walk through from DFT to optical properties]] and [[GW hBN Yambo Virtual 2021 version]] tutorials.<br /> <br /> ==Contents==<br /> In this tutorial you will learn how to:<br /> # [[Calculating optical spectra including excitonic effects: a step-by-step guide|Perform a Bethe-Salpeter calculation from beginning to end]]<br /> # [[How to analyse excitons - CECAM 2021 school|Analyse your results (exciton wavefunctions in real and reciprocal space, etc.)]]<br /> # [[BSE solvers overview|Solve the BSE eigenvalue problem with different numerical methods]] <br /> # [[How to choose the input parameters|Choose the input parameters for a meaningful converged calculation]]<br /> <br /> ==Links for schools==<br /> * Back to [[Rome 2023#Tutorials]]<br /> * Back to [[ICTP 2022]]<br /> * Back to [[CECAM VIRTUAL 2021]]<br /> * Back to [[ICTP2020]]<br /> * [[Modules|Back to technical modules menu]]<br /> * [[Tutorials|Back to tutorials menu]]<br /> <br /> &lt;br&gt;<br /> {| style=&quot;width:100%&quot; border=&quot;1&quot;<br /> |style=&quot;width:15%; text-align:left&quot;|Prev: [[Tutorials| Tutorials Home]] <br /> |style=&quot;width:70%; text-align:center&quot;|Now: [[Tutorials| Tutorials Home]] --&gt; [[Linear response from real time simulations|Linear Response]]<br /> |style=&quot;width:15%; text-align:right&quot;|Next: [[Introduction to Real Time propagation in Yambo|Theory]]<br /> |-<br /> |}</div>
