We are excited to announce the three-week program "Axions in Stockholm, 2025," which will run from 23rd June to 11th July, 2025, at Stockholm University and the Nordic Institute for Theoretical Physics (Nordita). This program will bring together leading experts in axion physics — from fundamental theory and cosmology to astroparticle physics and experiments — to evaluate the field’s status, address critical questions, and explore promising new directions.
The program consists of two workshop weeks bookending a conference week. The workshops are limited to 50 scientists per week and will provide lots of room for discussions, collaborations and informal presentations, in addition to a few scheduled overview talks. The general conference week will bring together researchers from all subdisciplines of axion physics and include a large number of invited and contributed presentations, in addition to panel discussions on topics of particular interest.
This program is a designated "Nordita program" and "EuCAPT workshop", and is sponsored by the Swedish Science Council through the "AxionDM" research environment grant.
