Hubbard workshop 2025

From September 22–26, 2025, we co-organized the workshop "The determination of Hubbard parameters: progress, pitfalls, and prospects" in Gandia, Spain. Together with David O’Regan, José J. Baldoví, and Young-Woo Son, our goal was to bring the DFT+U community together for an event that went beyond traditional presentations. In addition to scientific talks, the program was structured to include extended discussion sessions after each block, allowing participants to exchange ideas on challenges, open questions, and future directions. This format fostered lively, thoughtful, and collaborative debates that many participants found particularly valuable. We are grateful to our co-organizers, to José for the excellent local arrangements, and to David and Young-Woo for securing financial support from Psi-k and MARVEL. We also warmly thank all participants for their outstanding contributions, which made the workshop a real success. Encouraged by the positive feedback, we are already planning the next edition of the Hubbard Workshop, which will take place in Asia in the coming years.
