Nature of problem:
Calculation of excited state properties (quasiparticles, excitons, plasmons) from first principles.

Solution method:
Many body perturbation theory (Dyson equation, Bethe Salpeter equation) and time-dependent density functional theory. Quasiparticle approximation. Plasmon-pole model for the dielectric screening. Plane wave basis set with norm conserving pseudopotentials.

Unusual features:
During execution, yambo supplies estimates of the elapsed and remaining time for completion of each runlevel. Very friendly shell-based user-interface.

Additional comments:
yambo was known as "SELF" prior to GPL release. It belongs to the suite of codes maintained and used by the European Theoretical Spectroscopy Facility (ETSF) [1]

Running time:
The typical yambo running time can range from a few minutes to some days depending on the chosen level of approximation, and on the property and physical system under study.
