Frequently Asked Questions (FAQ)
What's with the name?
Don't worry about it, it's just a silly name. It doesn't stand for anything like
Yet Another Many-Body cOde, for instance. Unless you really want it to.
How should I cite Yambo?
We would appreciate it if you cited Yambo in any publications you make using the code.
The primary reference for Yambo is the article:
Yambo: an ab initio tool for excited state calculations
Andrea Marini, Conor Hogan, Myrta Grüning, Daniele Varsano
Comp. Phys. Comm. 180, 1392 (2009).
Can Yambo handle calculations based on Ultrasoft pseudopotentials?
No: only norm conserving pseudopotentials should be used with Yambo.
Can Yambo handle spin?
Yes. Since 27/02/2013 the GPL version of yambo can handle spin-polarized wave-functions and spinors. Check it out.
Why can't I check out the repository version?
Although access to the subversion repository is open to all, you need to register on the qe-forge portal
and upload your public ssh key. Log in, click "My Account" in the top right corner and add your public ssh key at the bottom of the page.
I want to reproduce result X from publication Y, but the version of Yambo I downloaded
doesn't seem to be able to do that kind of calculation. What's going on?
Tough luck: not all of Yambo is available in the GPL version. Maybe wait a few years.
I found a bug in Yambo...what should I do?
Have a look at the source code, debug it, and send us a patch. That is: if
it really IS a bug.
The information I need is not in the documentation or in this FAQ. What should I do?
Slowly but surely as we get more feedback, we will improve the user experience and support.

How do you get down off a horse?
You don't: you get down off a duck.
