Workshop

Spring Workshop on Quantum Gravity

April 26 (Wed) - 28 (Fri), 2023

This is co-hosted by iTHEMS and NCTS, and is also the first of Quantum Gravity Gatherings. What is space-time? How did the universe begin? Various approaches exist toward theories of quantum gravity that can answer such fundamental questions. Each approach has its own strengths and weaknesses and should capture, at least partially, some essential aspect of quantum gravity. Then, what are the general properties (if any) of the quantum nature of gravity independent of the details of such approaches? As the main speaker, we have asked Hikaru Kawai to give an intensive talk approaching this question from both general and specific arguments in a style consistent with the concept of Quantum Gravity Gatherings. We hope that the younger generation will experience his powerful arguments based on his experience and deep insights. This workshop is intended to be a lively and participatory event, not just a listening experience. For this reason, the number of participants will be limited to about 30 with priority given to graduate students and young post-docs; the intensive talk will be given in a face-to-face blackboard style (in English, no online streaming) to allow for informal and lively Q&A discussions. In addition, there will be sessions where any participant can give a short talk on any topic of his/her choice. Through these, all the participants will discuss the above question from various angles, and the young generations in Japan and Taiwan will stimulate each other and start new exchanges.

Connecting the hierarchies: from cosmos to life

February 20 (Mon) at 10:00 - 16:45, 2023

Yuki Yokokura (Senior Research Scientist, iTHEMS)
Etsuko Itou (Senior Research Scientist, iTHEMS)
Catherine Beauchemin (Deputy Program Director, iTHEMS)

As each research field in modern science has matured and become more sophisticated and deepened, it has also created the problem that it has become too fragmented from the perspective of the field as a whole. On the other hand, looking at individual research themes, research that connects different hierarchical structures, such as cosmogenesis and particle theory, neutron stars and nuclear theory, large-scale structure of the universe and formation of galaxies, stars, and planets, turbulent phenomena over a wide range of scales, life and non-equilibrium phenomena, etc., is progressing, and efforts to understand physical phenomena from an integrated perspective is spreading. The term "hierarchy" can also be interpreted as a hierarchy of theories, different principles and perspectives. Therefore, in this TJR workshop, we invite relevant lecturers from external institutes to give talks focusing on how they are striving to link different hierarchies in their respective research fields, with the aim of broadening our research perspectives and inspiring future research. Of course, the purpose is also to inform and inspire the younger generation about cross-disciplinary research topics.

Kyoto Univ. MACS Program x RIKEN iTHEMS Collaborative Research Forum

February 13 (Mon) at 13:00 - 18:00, 2023

RIKEN iTHEMS and the SACRA Interdisciplinary Research Division of the Graduate School of Science, Kyoto University signed a joint research agreement on the task "Creation of new fields and solution of various problems in science using mathematical-based interdisciplinary methods", which started in 2018, and the two institutions have been strengthening collaboration over the past five years. During this period, various collaborative activities in both research and education have been carried out and results have been achieved, including the holding of research symposia, joint lectures across universities, the establishment of visiting lectures, and educational activities in the MACS Study Group. At this forum, we would like to present the results of these five years of joint research and to link them to the start of further collaboration in the future. In particular, many undergraduate and graduate students have participated in the "MACS Study Group 2022-SG5 Pipeline Connecting RIKEN and MACS", and have been actively engaged in research activities with RIKEN researchers. The results of these SG5 activities will be presented by the students.

The second Tohoku University - RIKEN joint workshop, entitled "Math Meets Quantum Materials," takes place from September 29 - 30. Tohoku University and RIKEN have been holding a series of joint workshops based on the agreement on collaboration and cooperation signed in 2019. The second workshop focuses on collaboration in the fields of mathematical sciences and quantum materials; two fields that have significantly merged in recent years. Like topological materials, which are discovered using the mathematical concept of topology, materials science is currently evolving from the conventional way of finding materials. Instead of developing materials with good properties through numerous experiments, materials science is increasingly finding materials using mathematical predictions. This workshop will discuss these latests developments and related topics. Although some lectures will take place in Japanese, the majority of talks will be in English. The deadline for registration is Monday, September 28. For more information, please click on the relevant link.
