We organized an informal workshop to bring together staff scientists to showcase some of the software being developed for x-ray spectroscopy, both in and out of equilibrium. These include FEFF, as well as a broad set of codes related to FEFF (like OCEAN, RT-SIESTA, etc.) accessible via a simple interface (CORVUS); web-based ARPES, XAS, and multiplet-based x-ray absorption and resonant inelastic x-ray scattering (RIXS) codes; and software for strongly correlated systems (DMRG). These codes are now available free of charge to SLAC staff scientists and users of the facilities and can be accessed @ times.stanford.edu/resources.
We've been hard at work developing these things, so we were delighted to share them and get feedback on them. More generally, we would hope that workshops like this can help us to get to know each other better and encourage more collaborations between all of us.
