Tutorials standalone

These tutorials are self-contained and cover a variety of mixed topics, both physical and methodological. They are designed to be followed from start to finish in one page and do not require previous knowledge of yambo. Each tutorial requires download of a specific core database, and typically they cover a specific physical system (like bulk GaSb or a hydrogen chain). Ground state input files and pseudopotentials are provided. Output files are also provided for reference.

These tutorials can be accessed directly from this page of from the side bar. They include different kind of subjects:

Warning: These tutorials were prepared using previous version of the Yambo code: some command lines, variables, reports and outputs can be slightly different from the last version of the code. Scripts for parsing output cannot work anymore and should be edited to work with the new outputs. New command lines can be accessed typing yambo -h
