Seminar Report
iTHEMS Biology Seminar by Koichiro Uriu on December 12, 2024
On December 12, Dr. Koichiro Uriu presented a talk at the iTHEMS Biology Seminar titled "Mechanism for Converting Temporal Rhythms into Spatial Patterns of Body Segments." A former member of iTHES, Dr. Uriu is currently an associate professor at the Institute of Science Tokyo (formerly Tokyo Institute of Technology). In his talk, Dr. Uriu explored the fascinating mechanisms behind somite formation that serve as the basis for the backbone and other components of the body. While this problem has intrigued biologists for decades, it has remained a challenging and elusive subject of study. Using a combination of theoretical model and experimental data, Dr. Uriu and his collaborators uncovered a spatiotemporal bifurcation structure underlying vertebrate segment formation. This discovery suggests a potentially universal mechanism shared across multiple species. The presentation was concise and accessible, offering clarity on a complex topic. He adeptly answered questions during and after the talk, addressing not only the details of pattern formation in biology but also its evolutionary implications. At the dinner following his seminar, Uriu san shared valuable career insights, including strategies for delivering successful job interviews. We extend our heartfelt thanks to Dr. Uriu for the great seminar. Reported by Gen Kurosawa

DEEP-IN Seminar by Elia Cellini on December 18, 2024
The speaker Elia Cellini, PhD student at the University of Turin, introduced Markov Chain Monte Carlo methods and their non-equilibrium modification based on Jarzynski's equations. The non-equilibrium transformations can be also implemented efficiently using normalizing flows, powerful neural networks that represent transformations between probability distributions. Applying normalizing flows and non-equilibrium MCMC, the speaker showed how to approach difficult problems in lattice gauge theories, such as computing entanglement entropies.

On Oct. 14 (Mon) - Nov. 15 (Fri), a long-term workshop "Hadrons and Hadron Interactions in QCD -- Experiments, Effective theories, and Lattice -- (HHIQCD2024)" was held at Yukawa Institute for Theoretical Physics (YITP), Kyoto University. The week of Oct. 28 (Mon) - Nov. 2 (Fri) was held as "Nishinomiya-Yukawa symposium". The workshop was sponsored by YITP and supported by RIKEN-iTHEMS and several JSPS/JST programs. We had 193 participants from all over the world, with most of them attending in-person. There were 64 invited talks and 49 contributed talks. The international school, "Introduction to QCD and related topics", was also held and 5 lectures were given. The purpose of this HHIQCD2024 workshop was to bring researchers in lattice QCD, various effective field theories and also experimentalists together and make extensive discussions on hadron physics. Furthermore, the workshop also focused on formal developments of quantum field theories and frontiers of first-principle calculations (quantum computation and tensor network methods). The workshop expected to bring a new direction of researches to understand the nature of QCD. This long-term workshop was a "stay-and-discuss" style workshop in a relaxed atmosphere, where each participant was encouraged to stay long. With this style, participants had intensive discussions with other participants, and even started new collaborations during the workshop.

Seminar Report
Quantum Computation SG Seminar by Dorota Grabowska on December 6, 2024
The seminar speaker introduced the topic of Quantum Computations for Lattice Gauge Theories (LGT). Classical methods to solve LGTs are very advanced and allow researchers to connect the Standard Model of Particle Physics and its predictions to collider experiments. Some important phenomena arising in the Standard Model can not be explored with classical algorithms, and they may benefit from quantum computers. The seminar introduced the important aspects of research needed to understand how to define LGT in the Hamiltonian formulation. For example, how to define the Hamiltonian and its symmetries. Or how to choose the basis of the quantum operators on the lattice. Many interesting discussions followed the seminar. Reported by Enrico Rinaldi (Quantinuum / iTHEMS)

iTHEMS Biology Seminar by Hirokazu Fukuda on October 17, 2024
On October 17, Dr Hirokazu Fukuda delivered a thought-provoking presentation titled “Digital Twinning of Plant Internal Clocks for Robotics and Virtual Reality Enhancements in Agriculture.” In Japan, the agricultural workforce has decreased by more than 30% over the past decade, creating a growing demand for technological innovations like robotics and AI to support the industry. Dr Fukuda shared his theoretical research, which focuses on understanding so-called, biological clocks that regulate our physiological processes. He has applied this knowledge to operate plant factories, successfully cultivating crops such as lettuce. He emphasized the importance of real-time 3D simulations in future "AI plant factories," where robots will play a central role based on data gathered from sensors within the facility. During his presentation, Dr Fukuda highlighted the role of mathematical research, especially in developing predictive models for plant growth. The seminar, held via Zoom, attracted more than 30 participants and sparked an active and engaging discussion. Thanks Fukuda san for great presentation!! Reported by Gen Kurosawa

Press Release
Creation of the Quantum Universe and Precise Calculation of the Wave Function of the Universe
In modern cosmology, the idea that the universe was created from nothing through quantum effects has been a topic of active research. However, a long-standing debate has persisted regarding which of two prominent hypotheses—the no-boundary proposal or the tunneling proposal—is correct. A research team, including Hiroki Matsui (Postdoctoral fellow, Yukawa Institute for Theoretical Physics), Kazumasa Okabayashi (Postdoctoral fellow, Yukawa Institute for Theoretical Physics), Masazumi Honda (Senior Research Scientist, RIKEN), and Takahiro Terada (Research Assistant Professor, Nagoya University), has made significant progress in this debate by calculating the wave function of the universe from first principles, without the need for arbitrary assumptions about either proposal. Previous analyses left mathematical ambiguities unresolved, but this team eliminated those ambiguities using a method called resurgence theory. Their calculations rigorously demonstrated, under certain assumptions, that the wave function of the universe aligns with predictions from the tunneling proposal, not the no-boundary proposal. This result is a giant step forward in resolving the longstanding debate between these two hypotheses. For more details, please refer to the Kyoto University press release via the related links.

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.

Self-introduction: Yuuka Kanakubo
Hi, I’m Yuuka. I did my PhD at Sophia University in Japan, and moved to Finland and spent 2 years there as a postdoc at the University of Jyväskylä. Now, I have returned to Japan as a RIKEN-Berkeley fellow at iTHEMS. Since my PhD, I have been working on the development of Monte-Carlo event generators for relativistic nuclear collisions. I am generally interested in a collision of large and heavy nuclei, such as lead ions or gold ions, with a large mass number. The typical collision energy reaches up to a few TeV per nucleon pair at their centre of mass. With these experimental setups, we can generate an extremely hot soup of quarks and gluons, known as “quark-gluon plasma”. Relativistic nuclear collisions are dynamical processes with several different stages. I describe the collision process in full 3D and as dynamically as possible by sequentially applying different theoretical descriptions to each stage. For instance, I describe the production of quarks and gluons in the initial impact of colliding nuclei using perturbative QCD, the evolution of quark-gluon plasma with relativistic relativistic hydrodynamics combined with lattice QCD, and the interaction of hadrons in the final state using hadronic transport. I believe iTHEMS is an excellent research environment in this aspect as the study requires diverse knowledge in, for example, nuclear structure, perturbative and non-perturbative QCD, thermodynamics, methodology in Monte-Carlo simulations of many-body systems etc. I am excited to discuss with people from various fields and hope to find new solutions or new ideas!

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!

Self-introduction: Gabriele Di Ubaldo
I am broadly interested in understanding quantum gravity as an emergent phenomenon. This is the case in the AdS/CFT correspondence where a d+1-dimensional theory of quantum gravity (usually a string theory) emerges from the collective dynamics of a d-dimensional Conformal Field Theory (CFT) with many degrees of freedom. I believe this is a beautiful example of Anderson's principle "More is different", where many-body quantum systems (the CFT) can exhibit striking and unexpected collective behaviour (Gravity). I am particularly interested in the role of quantum chaos and thermalization in the correspondence between CFT and black hole physics and how to explain and derive gravitational phenomena, such as wormholes, using CFT and the tools of the conformal bootstrap. More broadly, I am interested in many-body quantum systems, disordered systems, classical and quantum chaos, and diverse topics in math, such as random matrix theory, analytic number theory (modular forms), topological recursion, and three-manifold geometry. If you are working on any of these topics or are simply interested, I'll be happy to talk physics! Previously, I obtained my PhD at the Institut de Physique Theorique in Paris, CEA Saclay, working with Eric Perlmutter, and my master's degree at Ecole Normale Superieure in Paris. Looking forward to my time at RIKEN and UC Berkeley!

NCTS-iTHEMS Joint Workshop on Matters to Spacetime: Symmetries and Geometry on August 26, 2024
The 1st NCTS-iTHEMS Joint Workshop was held from August 26th to August 29th, 2024, at the National Center for Theoretical Sciences (NCTS), National Taiwan University, Taipei, Taiwan. The event was co-hosted by NCTS and RIKEN's Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program. A total of around 50 participants from Japan and from Taiwan attended the workshop. The workshop aimed to foster collaboration in the fields of condensed matter physics and quantum gravity, bringing together experts to share the latest research developments, explore interdisciplinary connections, and identify opportunities for joint projects. It marked the launch of an annual series of joint workshops between NCTS and iTHEMS, with alternating hosts. The program alternated in each session on one day between condensed matter physics and quantum gravity topics to promote interdisciplinary collaboration. This alternating format encouraged researchers to engage with ideas outside their primary field, stimulating innovative approaches and broadening the scope for joint research. The four-day workshop included 23 talks, covering a range of topics such as topological superconductors, twisted bilayer graphene, quantum holography, and string theory. Some afternoon sessions were dedicated to informal discussions, promoting interdisciplinary exchange between participants. Researchers had the opportunity to explore potential collaborations, exchange ideas on shared problems, and identify future research directions. The 1st NCTS-iTHEMS Joint Workshop fostered collaboration between condensed matter physicists and quantum gravity theorists. By alternating topics each day, the workshop created a dynamic environment where researchers from both fields could engage with each other’s ideas, leading to cross-disciplinary innovations and future collaborative efforts. The next iTHEMS- NCTS Joint Workshop will be held in RIKEN Wako campus in 2025, with iTHEMS serving as the host. The long-term objective is to continue this tradition of interdisciplinary exchange, ensuring the involvement of a diverse set of researchers and further strengthening the research connections between NCTS and iTHEMS.

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!
