“Frontiers in Ab-initio Many-Body Interactions” (FAMBI 2026) was successfully held at Tohoku University, Sendai, Japan, on November 12–13, 2026. On behalf of the Organizing Committee, we would like to express our sincere gratitude to everyone who joined us in Sendai.

We were delighted to welcome more than 40 participants over the two days. The program comprised 9 invited talks, 10 contributed talks, and 14 poster presentations, and the workshop was marked by lively and fruitful discussions throughout, from the oral and poster sessions to the conversations during the breaks.

We are deeply grateful to all the speakers and presenters for sharing their work, and to all the participants for their thoughtful questions and active engagement, which made the workshop a great success. We hope that the discussions and connections initiated at FAMBI 2026 will lead to further progress in the field.
