FHI-aims Developers' and Users' Meeting 2023
ELECTRONIC STRUCTURE THEORY WITH NUMERIC ATOM-CENTERED BASIS FUNCTIONS
August 2 – August 4, 2023
In-person participation
at
Center for Free Electron Laser Science (CFEL)
Luruper Chaussee 149, 22761 Hamburg
This workshop will explore advanced methods in electronic structure development that are based on localized, numeric atom-centered orbitals (NAOs). NAO-based modeling is widely considered to be one of the most powerful approaches to studying molecules and materials from a first principles perspective. To advance the state of the art in this area, the proposed meeting will bring together key players from the FHI-aims code and related European and international efforts. Participants will have the opportunity to share their insights, discuss emerging trends, and collaborate on new research initiatives.
Important Dates
| April 15, 2023 | Registration Opens |
| May 31, 2023 | Registration Closes |
| Early June, 2023 | Acceptance announcements |
| August 2, 2023 | Start of the Conference |
| August 4, 2023 | End of the Conference |
Scope
The workshop will cover three days and 20 invited talks, as well as a poster session. Time will be reserved in the afternoons for “Hands-On Discussions”, providing dedicated time for the participants to split up into small groups to focus on topics of specific interest ranging from methodological improvements all the way to code development questions related to specific subgroups of participants and joint programming sessions. Participants are also able to present their own work during the Postersession.
Topics covered are new developments in electronic structure theory with numeric atom-centered orbitals - including, but not limited to:
- Numerical algorithms and new methods for NAOs
- Technical advances in and scalability of electronic structure methods
- External libraries interfacing with FHI-aims
- Recent developments in advanced electronic properties
