Farewell message from Liang Zhang
Our colleague, Liang Zhang, has returned to the Shanghai Institute of Applied Physics at the University of Chinese Academy of Sciences to complete his PhD thesis. We will all miss him and wish him the very best of luck in successfully defending his thesis ! Here is a message from Liang Zhang: I joined iTHEMS in January 2023 as a joint student and completed my two-year journey here in January 2025. I initially joined iTHEMS to study lattice QCD and the HAL QCD method, and I am deeply grateful to Hatsuda-san and Doi-san for guiding me into this fascinating field. However, I soon realized that my experience at iTHEMS extended far beyond my original purpose. For example I had a discussion with Namba san on chiral symmetry breaking which is studied in both particle physics and cosmology. It left an immediate impression that physics is so universal other than reading such sentences in textbooks. And the interdisciplinary energy at iTHEMS constantly amazed me. When I first came here I always struggled to pinpoint people’s major. In some seminars, theoretical physicists gave a biology talk (like Christy)! I vaguely feel like there is a group theory for nature which can be expressed to different representations, biological, mathematical, physical, etc. Is this what the “i” in iTHEMS means? At last I would like to thank everyone in iTHEMS again for my two-year experience here. This experience gives me a great impulse to expand the possibilities of my future research life. iTHEMS’s uniqueness lies in its boundless possibilities. And I dearly hope our paths will cross again!

I am especially grateful for iTHEMS directors and colleagues' support in starting the "asymptotics in astrophysics" iTHEMS study group, ample chances to travel abroad to share my work, and the frequent international workshops organised at iTHEMS. In particular, workshops co-hosted with RIKEN-Berkeley left this lasting impression on me; that new stellar astrophysics and supernova physics paradigms are creatively and efficiently conceived when physicists, mathematicians and data scientists join forces to solve longstanding astrophysical puzzles. iTHEMS is such a special place where those necessary first interactions are regularly facilitated, and I am sad to leave. But... "I'll be back"!

We all will miss him and wish him the best of luck in his latest endeavor. Here is a message from Yantao Wu: I joined iTHEMS in June 2021 as a RIKEN-Berkeley fellow, and have stayed here for three years and a half now. iTHEMS is a precious rare place in the academic world, where there seems to be no responsibility, no one telling you what to do, and infinite space for travel; where there seems to be a curious mind on every subject and every question ought to be asked. The interdisciplinary nature of the group has forever left an imprint on me, and I will always remember the vivid biological facts and mathematical tricks that I have learned here. Entering as a condensed matter physicist and leaving as a condensed matter physicist, my heart will always have a spot for the particle theory which I have learned from here. It has been an unexpected, yet very pleasant mix. Sadly, it appears that every gathering ends somewhere, and I need to leave this warm and protective bubble to a new place, to really enter the grown world of independent research and start my own group. iTHEMS will always remain as a source of lasting encouragement. I will move to the Institute of Physics, Chinese Academy of Sciences in Beijing to start a faculty position. If you ever want to visit, please let me know you are from iTHEMS and I will make you a cup of tea (amidst taking you to the great wall and covering your travel costs.)

Hot TopicRIKEN Quantum Workshop on “Quantum-Like Modeling in Cognitive & Social Sciences" on October 11, 2024
On Oct. 11 (Fri), RIKEN Quantum Workshop on “Quantum-Like Modeling in Cognitive & Social Sciences” was held at Room 359, Main Research Building, RIKEN (Wako). The workshop was hosted by RIKEN Quantum and had 30 participants from a variety of fields, including cognitive and social sciences as well as life sciences, mathematics, and physics. This was the first workshop at RIKEN to discuss “Quantum-Like Modeling” for various phenomena in cognitive and social sciences. “Quantum-Like Modeling” suggests that using quantum probability calculus and its applications could be useful to rationalize cognitive and social phenomena as open quantum systems and expand previous understandings, obtained through simple linear algebra, by applying quantum formalizations. After Atsushi Iriki, one of the organizers, explained the purpose of the workshop, there were four invited talks. Andrei Khrennikov gave a comprehensive talk on applications of the methodology and formalism of quantum theory outside of physics, in cognition, psychology, decision making, social and political sciences, economics and finance, genetics and evolutionary biology. Masanao Ozawa gave an introduction to his proposed quantum instrument theory, which unifies quantum measurement and quantum cognition through quantum simulation. Haruki Emori talked about applications of quantum computers to cognitive sciences based on the quantum instrument theory. Finally, Miho Fuyama introduced her empirical research on subjective experiences and superposition states of quantum probability theory in narrative reading. These invited talks were followed by a general discussion and networking mixer, which deepened understanding of “Quantum-Like Modeling” in cognitive and social sciences from various perspectives and promoted new networking among the participants.

Presentation of iTHEMS outreach at NuFACT conference
iTHEMS is a fantastic environment in which we conduct interdisciplinary research daily. Along with our research activity, a variety of outreach activities have been conducted so far. Tomoya Nagai (Coordinator, iTHEMS) presented this special environment and its outreach activity at the NuFACT 2024 conference. At the conference, a session for Inclusion, Diversity, Equity, Education, and Outreach (IDEEO) was composed. The session itself was organized so that we could visualize diversity in terms of speaker's and convener's properties. It provided us with a good opportunity to know IDEEO-related activities all over the world, which can be a chance to recognize and reconsider the issue around to achieve "good environments for everyone". One special example of the iTHEMS outreach was the "Journalist in residence" program. The uniqueness of the activity caught significant attention from the participants of the conference. Also, "Mathematics Connecting to the World: One S&T poster for Every Household" seemed to be intriguing. Although we had only a limited time for this exhibition and discussion, Nagai's attendance brought the conference a fresh view of the outreach activity as well as the achievements of the interdisciplinary and diverse environments. iTHEMS can be so influential to our community in multiple contexts!

Here is a message from Eiji Inoue: I spent three and a half years in iTHEMS as an SPDR on math. I would like to thank the program director and assistants for their mindful support over these three and a half years. I also wish to thank iTHEMS members for discussion on many occasions. These years I spent in iTHEMS were invaluable for me. Among all, the best experience for me was that I could gradually get a feeling on "physics in the real world" not only mathematical structure of physics, from the choice of words physicists use in daily discussion. In these casual discussions, I could also try if my understanding of physics are correct. I also enjoyed playing quantum computers. I think it was impossible to experience without this tolerant environment of iTHEMS; indeed, it just started from a casual conversation with the director. It was the first time I experienced quantum phenomena, especially quantum entanglement, in the real world where I exist. This may sound a little strange, but I feel like I haven't had that feeling of interest in how the real world works in a long time. While I was going through these experiences like a newborn child, as a mathematician, I could finally achieve my original project on Perelman entropy in the last half year during my visits to Cambridge, Montreal and Aarhus. There are still many thigs to do, but this is certainly the foundation of this new theory. One regret is that I could not finish writing a paper on this result while enrolled at iTHEMS. I'll be an assistant professor at Kyoto University (Department of Math) from October. I welcome people from iTHEMS to come to Kyoto and discuss. I will also ask iTHEMS for help. See you again!

Professor, how many dimensions does "space" have!? ── Asking Theoretical Physicist Yasunori Nomura about the Nature of "Space" from Subatomic to Cosmic Scale
In VOL.53 of the Japanese edition of the magazine 'WIRED,' we delve deeply into the potential of "space" × "computing." However, how should we define the very essence of "space"? A superficial exploration would undoubtedly result in a half-baked understanding. Therefore, we sought the wisdom of one of the foremost theoretical physicists of our time. We visited the office of Yasunori Nomura on the 4th floor of the Physics Department building at the University of California, Berkeley (UC Berkeley). Professor Nomura, what exactly is "space"? What is space? This question is directly related to the progress of modern physics. It can be said that modern physics is a discipline that seeks to understand "space and time." So, before delving into the perspective of quantum gravity theory, which is my specialty, I would like to briefly explain the relationship between physics and space. For the continuation, please visit the WIRED website through the related link.

Seoul National University student group visited iTHEMS on January 10, 2024
On Wednesday, January 10, a group of 22 undergraduate students part of a student group called GLEAP from Seoul National University (SNU) came to visit iTHEMS, accompanied by Professor Ji-Young Lee, Associate Dean of the College of Natural Sciences in the School of Biological Sciences at SNU. The students were from various years (2nd to 4th year undergraduates) and a wide range of scientific fields, including mathematics, chemistry, biology, physics, and statistics. Their visit to iTHEMS was part of a several days' tour of various Japanese universities and research institutes, to consider their future career opportunities and research directions. Upon arriving at RIKEN, the group was greeted by iTHEMS members Dongwook Ghim and Catherine Beauchemin, and were first taken on a tour of the Nishina Center ion beam accelerators. They then enjoyed very brief, casual conversation in the iTHEMS common rooms with some snacks. Catherine Beauchemin gave a 5-min introduction of the various opportunities for SNU students to become iTHEMS members in the future (e.g., JRA, IPA, SPDR, RS/SRS). Then 6 different iTHEMS researchers (Dongwook Ghim, Misako Tatsuuma, Akinori Tanaka, Catherine Beauchemin, Steffen Backes, Ryo Namba) gave great 12 min talks about their research, and some additional iTHEMS members also joined. After that, several additional iTHEMS members joined and each of the students and iTHEMS members briefly introduced themselves and their research interests. This was followed by interesting, casual discussions between iTHEMS members and the SNU students over light food. The students told me they thoroughly enjoyed their visit to iTHEMS and learning about the wide range of research our members conduct. Overall, this provided a great opportunity to showcase iTHEMS members' research to young researchers considering their future academic career. Many thanks for the amazing support provided by all the iTHEMS assistants without whom this event would not have been possible, to the iTHEMS researchers who took their time to take part in this event and make it so interesting for the students, and with special thanks to Dongwook Ghim, himself is a graduate of SNU, for all his help and for being such an inspiring role model for these students of his alma mater.

Black Hole Recorder was exhibited at the art event DIG SHIBUYA from January 12th to 14th, 2024
iTHEMS exhibited "Black Hole Recorder”, a science art work based on quantum black hole theory created in 2021 with outside creators, as a program within the art event "DIG SHIBUYA” at the Shibuya Workers’ Welfare Hall for three days from January 12 (Fri.) to 14 (Sun.). The entire event was organized by the SHIBUYA CREATIVE TECH Executive Committee in cooperation with the Shibuya City, and "Black Hole Recorder” was selected as a collaborative project through an open call for proposals. The exhibition was held in a dark room with the "Black Hole Recorder” set up in the middle of the room, and visitors were invited to enter with a flashlight to illuminate their feet and view the works with explanations. The entire venue was an experimental space, and the "Black Hole Recorder” constantly recorded all the sounds in the venue. For the first time, a booth was set up to allow visitors to listen to environmental sound data recorded from the very experimental space where the "Black Hole Recorder” was exhibited in the past, allowing them to enjoy the experience of listening to the past. The exhibition was held at a facility located in the city of Shibuya, where many people (close to 300 in total) gather, and many visitors were able to view and experience the exhibition on a holiday day. Depending on the time of day, the venue was sometimes quite crowded. Through the artworks, many visitors became interested in black holes and their theories, and I believe that many of them left with an image of a black hole. Detailed explanations of the theory using a blackboard by researcher Yuki Yokokura and program director Tetsuo Hatsuda were also well received. The response was also positive due to the sense of time and scale regarding the plan to send recorded sounds to a black hole via radio waves in the future in order to deliver the sounds of humanity far into the future. Exhibiting at an art event in the city provided an opportunity to bring the results of our research to people who are not usually interested in science, and we felt that this was a good opportunity to make progress in the future.

Here is a message from Yalong: I am deeply in debt of gratitude to Hatsuda san and all iTHEMS assistants for their generous support over the two and a half years which I spent in iTHEMS. To mathematicians, maybe the most important thing is to have an environment where we can freely develop things that fascinate us, which might not be useful for something else immediately. It is a great fortune to me that iTHEMS provides such an environment. Besides that, I have been enjoying discussing with our lovely members and also wandering in the beautiful Wako campus (especially during Spring and Autumn), which helps to refresh me all the time. I will move to the Chinese Academy of Sciences in Beijing to work and become a visiting scientist of iTHEMS. I hope to come back to visit regularly and continue to enjoy everything here. Everyone is surely very welcome to visit me in Beijing. Let's keep in touch and keep enjoying our life and career.

On Friday 21st April, Thomas Hitchcock gave a short talk at Nerd Nite Tokyo entitled “Sex Education: reproductive diversity across the tree of life”. There he talked to a general audience about the range of ways that organisms may reproduce, from those organisms that simply make copies of their own genes (asexual reproduction), to those that mix them with others (sexual reproduction), and those that can do both (facultative sex). He discussed the different mechanisms that organisms may use to decide whether to reproduce as a female (producing eggs) or male (producing sperm), and how genes may pass differently to offspring through these two routes, illustrating these ideas with stories about spoonworms, fungus gnats, and rotifers. Finally, he stressed how evolution may work differently in these different reproductive systems, and so the importance of understanding this diversity for guiding our efforts in conservation, agriculture, and medicine.
