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.)

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!

Farewell message from Eiji Inoue
Our colleague Eiji Inoue will move on to a new career as an assistant professor at Kyoto University as of Oct. 1, 2024. We all will miss him and wish him the best of luck in his latest endeavor. 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!

Our colleague Yalong CAO will move to the Morningside Center of Mathematics and the Institute of Mathematics at the Chinese Academy of Science in Beijing as an Associate Professor, starting from Jan. 9, 2024. We all wish him success in his new affiliation! 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.

Thomas Hitchcock gave a short talk at Nerd Nite Tokyo on April 21, 2023
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.
