International workshop: ``Clusters in quantum systems: from atoms to nuclei and hadrons"

Clusters are aggregates of microscopic objects or particles, formed when they attract each other. While they appear in various forms at various scales, there is growing evidence that some types of clusters governed by quantum mechanics exhibit the same universal features. Prime examples are the Efimov trimers observed in cold atoms, few-nucleons systems following the Phillips line, and neutron-rich "halo" nuclei. There are also ongoing attempts to find exotic hadronic molecules or neutronic molecules by using leading accelerator facilities around the world. How are these few-body clusters different from each other? Can we find the same universal features despite the extreme difference in energy scale between them? This workshop aims to be a platform for researchers working on these clusters in various fields of physics to reach a universal understanding across the different scales of these fields. The workshop will be held at Tohoku Universisty (Aobayama-campus) in Sendai. It will consist of two kinds of sessions. The first one will be dedicated to presentations by participants, to share recent results in different fields. The second one will provide free time to the participants to stimulate discussion and collaboration, aiming to lead to future new directions of interdisciplinary research.

The building of Frontier Research Institute for Interdisciplinary Sciences(FRIS) is indicated by green simbol in the above googlemap and dark blue on the bottom panel. It is located at Aobayama campus of Tohoku Uniersity in Sendai. It is 1-2 minutes walk from the train station, Aobayama (青葉山) station of the metro line called Tozai line (東西線). Aobayama (青葉山) station is about 15 minutes from Sendai (仙台) station with Tozai line (東西線). From the airport SDJ, you can first take a train, Sendai-Airport Access line, to Sendai (仙台) station (about 20miutes). Then change to the metro Tozai line (東西線) toward Yagiyama Zoo direction. There is another different metro line, so be careful not to take the different metro. See here for more detals
