RIKEN-Vancouver Joint Workshop on Quantum Computing was held on August 24-25, 2021
RIKEN-Vancouver Joint Workshop on Quantum Computing was held online on August 24-25. The main aim of this workshop is that the quantum people in RIKEN (iTHEMS and RQC) and Vancouver (Quantum BC) get together online to discuss scientific activities and explore future collaborations. There were altogether 164 registrations (90 from Japan, 62 from Canada and 12 from other countries). 12 scientific talks were presented together with 3 introduction to iTHEMS, RQC and Quantum BC. From iTHEMS, Jason Chang, Etsuko Itou, and Takumi Doi gave talks respectively on the Schroedinger equation, the U(1) gauge theory and combinatorial optimization. After each session, there were one-hour breakout sessions, so that people can ask further questions to the speakers, which worked very well. The workshop was an excellent first step toward a close tie between RIKEN quantum activities and Vancouver quantum activities.

The work of a research group, including Dr. Maria Dainotti and Enrico Rinaldi, has been featured in several institutional press releases and websites
The work of a research group, including Dr. Maria Dainotti and Enrico Rinaldi, has been featured in several institutional press releases and websites. One of the most famous open problems of modern cosmology is the Hubble constant (H0) tension. This consists in the discrepancy (>4 sigma) between the values of H0 measured with the late universe local probes, namely the Supernovae Ia (SNe Ia), and the early universe observations, the Cosmic Microwave Background (CMB) radiation. With our investigation we found that a slow evolution with redshift is present in this constant thus allowing to alleviate this discrepancy. The study is published in ApJ. The investigation started when Dr. Maria Dainotti (now Assistant Professor at NAOJ) and Enrico Rinaldi (now Research Fellow at Michigan University) were Senior Research Scientist and Visiting Scientist both at iTHEMS, respectively. See related links for details.

iTHEMS x academist online public event was held on April 18, 2021
Following last year’s precedent, iTHEMS held an online lecture event for the general public with the help of Academist Inc., on April 18th, 2021. The event was planned as an alternative for the lectures at RIKEN’s annual open house. The event was started by Kanato Goto with his talk on Blackhole and its information problem. His compelling narrative evoked a lot of questions from high school students; some of them were very sharp. Next, Jeffery Fawcett talked about genome science. Among other topics he studied, he also mentioned the mutation of COVID-19 virus. During the lunch break, Program Director Hatsuda talked with Mr. Shibato from Academist about related books, the exhibition of Black Hole Recorder at Miraikan, and the attempts with RIKEN SUURI. In the afternoon, Sugiura-san talked about the supercomputers and the analysis of subatomic physics, followed by Naomi Tsuji's talk on supernovae and their remnants. The talk included several polls from the audience. Keita Mikami concluded the event with his talk on Mathematics, in particular inequality and differential equations. All the talks were compered by Ms. Michibayashi from Academist; Her facilitation with a wit kept the talks accessible even to high school students. The event was viewed by as many as more than three hundred audiences at one time.

Message from the Director at the end of FY2020
I would like to thank all the iTHEMS members and iTHEMS supporting staff for your great efforts to keep iTHEMS very active during FY2020 even under the Covid-19. Our iTHEMS mission is very simple. Good science under the environment of interdisciplinary interactions: "A+B --> A*, A+ B --> B*, A+B --> C" are all in line with this mission. We will have many newcomers joining iTHEMS from FY2021, and let us keep moving forward without boundaries. Now, I would like to congratulate the two iTHEMS students: Toshihiro Ota (student trainee from Osaka Univ.) and Keisuke Fujii (student trainee from Tokyo Institute of Technology) who successfully defended their Ph.D. and are going to graduate from their Universities and from iTHEMS. I hope you have enjoyed your stay in iTHEMS and let us keep in touch for further interactions. Last but not the least, I would like to thank our assistant Izumi Nagasawa who has made tremendous support for the web page, seminars, colloquiums etc and is leaving iTHEMS at the end of this March. Although we could not see her so frequently in person under Covid-19 situation, she has been really helping our activities from behind. We send her our heartfelt gratitude.

小澤准教授のインタビュー記事がイスラエルの雑誌「Epoch」に掲載
AIMRジュニア主任研究者の小澤知己准教授のインタビュー記事が、イスラエルの一般向け雑誌「Epoch」の2020年12月号に掲載されました。 記事では、小澤准教授が進めている「人工次元」に関する研究が詳しく紹介されています。私たちは３次元空間に住んでいますが、最近通常の次元とは違って人工的に次元に相当するものを作り出し、それに関する実験・研究ができるようになってきました。 小澤准教授は原子のふるまいであるスピンを例に挙げて説明しています。スピンが取る状態を次元とみなせば、４次元量子ホール効果など高次元空間に関する物理現象などを実験的に研究できるようになるとの見解を述べています。 記事は高次元に関する最新の研究を、SFのような並行宇宙（パラレル・ユニバース）などとも関連させて解説した一般向けの内容ですが、人工次元という新しい概念もわかりやすく解説されており、非常に興味深い内容となっています。人工次元に関する研究が物性物理から素粒子物理まで様々な分野に影響を与えることが期待されます。

Farewell message from Dr. Martin Skrodzki
When my scholarship program first notified me that I would be able to spend a year, working in the RIKEN iTHEMS program, I was extremely happy for this great interdisciplinary and intercultural opportunity. Now, this year has ended and I will return to Germany to continue my research there and possibly at other locations in Europe. I arrived at RIKEN iTHEMS on January 20. While I expected the year to be very exciting, I did not at all imagine what 2020 had in store for all of us. After my first talk in the math seminar, we went to an Izakaya and had a Nomikai there. From the current perspective, this appears quite unreal to me. The Covid-19 pandemic caused this year to be run quite different from any other year. We all had to get used to working from home, working online, and even enjoying each other’s company during online coffee as well as online parties. Despite these restrictions, I tremendously enjoyed my stay in Wako and in Japan in general. Several aspects at iTHEMS contribute to a very friendly and positive atmosphere in the program. For instance, the coffee afternoons were a great way throughout my first couple of weeks to get to know many members of the workgroup. Also the all-hands coffee meetings on Friday are a great installment to stay in touch with each other. Furthermore, the dedicated math seminars were great for me to get new input, learn new mathematics, and chat with the colleagues. The organizers of the math seminar, but also all other chairs and the speakers, made the seminars very enjoyable events. Aside from these events, I was very happy to pursue my own research projects. As I am in the first phase of my postdoctoral career, this was a great opportunity to sharpen my research foci. Thus, I would like to close by thanking everyone for making my stay at RIKEN iTHEMS as enjoyable as it was. Once the global situation has settled down, I would love to return for a short visit or even another extended research stay. Let’s stay in touch!

Hello. I am Genki Ouchi, a special postdoctoral researcher in iTHEMS. I am leaving iTHEMS and moving to graduate school of mathematics, Nagoya university as an assistant professor. I joined iTHEMS on April 2018. Since then, it has been two and a half years. I learned a lot of things from iTHEMS. Before I came to iTHEMS, I was just an “algebraic geometer”. I studied only algebraic geometry and related topics. After joining iTHEMS, I got opportunities to learn other topics in mathematical science. Especially, I study network science with mathematicians, physicists and network scientists now. With an experience at iTHEMS, I become a “mathematician”. I wish that interdisciplinary activities in iTHEMS bear fruit over the long run. I would like to thank all iTHEMS members for your kind support and help. I am looking forward to seeing you again.

Workshop on Communication for Interdisciplinary Collaboration
On January 28th, iTHEMS member Don Warren co-hosted a workshop on Communication for Interdisciplinary Collaboration. The goals of this workshop were (1) to learn how to communicate with people who do not study the same topic you do, and (2) to practice explaining your work so that a non-expert can decide if they want to join your project. The workshop was open to all RIKEN staff in all fields and positions, and turnout was very good: scientists from multiple centers attended, as did several non-research staff. Everyone who attended learned two key points to make cross-discipline communication easier and more productive. First, listen actively when someone is talking about their work to you; don’t fixate on the first interesting thing and stop listening to the rest of their explanation. Second, K.I.S.S.—keep it short and simple! (It is easy to talk about what to do, but it was much harder to practice it during the workshop.) The workshop facilitator was Christiane Brew, a performer and trainer who uses techniques from improvisation to encourage open discussion, deep listening, and clear “pitching”. This was the second of two workshops organized in FY2019 by Don and Amanda Alvarez of CBS. Support for the workshop came from the RIKEN Collaboration Seed fund. If this workshop is repeated next year, please consider joining and practicing your communication skills so you will be ready to start on your next interdisciplinary collaboration.

Summary of interdisciplinary workshop "Present and Future of the Quantum Computing (QC)"
Interdisciplinary workshop "Present and Future of the Quantum Computing (QC)" hosted by MEXT and sponsored by iTHEMS and CEMS was held on Jan.29, 2020 at RIKEN Suzuki Umetaro Hall. There were more than 170 people got together from academia, industries and publishers. For the people who could not enter the hall, the talks were also broadcasted to the iTHEMS room 160. The scientific session was started with a review talk on the history of quantum-bit researches by Yasunobu Nakamura (CEMS). It was then followed by 11 talks which covered wide topics ranging from the QC architecture development to QC algorithms. The very last talk was given by our iTHEMS colleague, Jason Chang (iTHEMS/UCB), who discussed the adiabatic quantum computing and possible near-term engineering applications on the basis of his recent QC works. A poster session with about 30 posters from many different areas of science was also held with very lively discussions, especially among young researchers. Since the meeting was so successful to provide a platform for the researchers interested in this growing field of QC, we will definitely have the 2nd meeting in the near future.

Farewell note from Dr. Tomoki Ozawa
Hello. My name is Tomoki Ozawa. I am a senior research scientist at RIKEN iTHEMS. As of February, I am leaving iTHEMS and moving to Advanced Institute for Materials Science (AIMR) in Tohoku University, Sendai, to start my own group as an associate professor. I joined iTHEMS on April 2018; I cannot believe that it has already been almost two years. Time really flies like an arrow. Before joining iTHEMS, my research career has been developed abroad (US, Italy, Belgium), and although I am a native of Japan, iTHEMS is the first Japanese affiliation I obtained as a researcher. Before coming back to Japan, I had always been worried if I could be accepted to the Japanese academic community. After joining iTHEMS, I learned that my worries were needless. I was surprised by the welcoming atmosphere of iTHEMS, and even though I was the only condensed matter physicist in iTHEMS, I could easily find somebody to discuss in the iTHEMS coffee room. What helped me even more to place myself in Japan were the various satellite offices of iTHEMS in (and also outside) Japan. These satellite offices made it easy for me to visit and know what is going on in various other places in Japan. After spending almost two years in iTHEMS, although I am still constantly surprised by cultural differences between Japan and other places I have been, I feel that I have comfortably become a part of the academic community in Japan. In terms of research, what was great being in iTHEMS was that I could do whatever research I wanted to do, without any pressure on the selection of topic or to report what I am doing to my boss. I really appreciated the academic freedom here. I am also starting to build collaborations in Japan. The new collaborations I am building are quite interdisciplinary (including atomic physics, photonics, and even biophysics), thanks to the wide scope of interests of people in iTHEMS. It has been a real pleasure to spend time in the beginning period of iTHEMS, and I am sure that iTHEMS will flourish even more in the coming years. AIMR has a satellite office of iTHEMS, and I expect to maintain active interactions with iTHEMS after I move to AIMR. I will also most likely come to iTHEMS offices (perhaps the coffee room in Wako) from time to time, and I am looking forward to seeing the successful development of iTHEMS in the future.

All-RIKEN Workshop on Virtual Reality holds second session
The first All-RIKEN Workshop on Virtual Reality held an introductory session in October. Many visitors came to try out VR and assess whether they could use it for their own research. On Tuesday, November 26, the second session of the workshop took place. iTHEMS members Don Warren and Gilles Ferrand hosted the all-day, hands-on event. The two primary goals were (1) to teach attendees how to use Unity, the engine Gilles and Don use for their own VR demo, and (2) to let them get their own data into a 3-D visualization. In the first part of the day, participants created their own computer game, entirely from scratch. (If you know someone who attended, ask to play their game!) This introduction to game design showed people how Unity works, and prepared everyone for the second half of the schedule. In the second half, they learned about what kinds of data can be visualized in 3-D and in VR. They also got to use a basic visualization kit (developed by Gilles) to explore their own data in 3-D. There was a lot of good discussion about how to present data in a way that works for 3-D and VR -- some formats that work very well on paper do not translate well to 3-D space! By the end of the workshop, attendees had the tools needed to start exploring their own data. Gilles and Don hope that they will continue to think about this, to develop their skills in Unity, and to form a 3-D and VR visualization community at RIKEN.

Introduction of Hallatschek group and daily activities: Berkeley Report from Dr. T. Okada
Hi, everyone! In this short article, I will write self-introductiton, also about the laboratory I am belonging to at UC Berkeley and also write my daily activities there. My research interest is theoretical biology, including biochemical reactions, biological networks, evolutionary dynamics etc. I am currently working at Hallatschek laboratory as a long-term visitor, and mainly researching on theoretical aspects of evolutionary dynamics there. As a theorist, one of ultimate goals is to predict outcomes of evolution. Since evolutionary processes are very complicated even under well-controlled conditions, this project is very difficult, but, at the same time, very attracting theoretically. Hallatschek lab studies evolutionary biology both experimentally and theoretically. There are approximately 10 members (students and postdocs) in total, and a half of us do evolutionary experiments using microorganisms, such as yeast and E. coli, and a half of us (including me) study theoretical stuff. For now, I have three meetings in the group every week. The attached photo is one of the weekly meeting which I am doing with Jonas (postdoc, left) and Stephan (graduate student, right). I am very satisfied with the scientific atmosphere here, and I really appreciate the support by iTHEMS. Also, I think that in evolutionary biology, there are many topics that are interesting for many mathematicians and physicist, and I am looking forward to interacting iTHEMS members when I come back to Japan.

An international WS "Collaborative Meeting on Supernova Remnants between Japan and USA" was held at RIKEN Wako campus (Nov. 7-8, 2019) and SUURI-COOL Kyoto (Nov. 11-12, 2019) with Masaomi Ono (ABBL/iTHEMS), Shiu-Hang Lee (Kyoto Univ.) and Shigehiro Nagataki (ABBL/iTHEMS) as organizers. The aim of this workshop was to bring together experts including young researchers on supernova remnants and other related topics, such as supernovae, progenitor stars, and neutron stars, for active discussion and to initiate possible collaborations among the participants. In both 1st and 2nd weeks, there were about forty participants. Experts from USA mainly on supernova remnants gave excellent talks from both aspects of theories and observations. Not only supernova remnants but also many other related topics were presented by participants from Japan and Taiwan including students. During the workshop, many possible future collaborations were intensively discussed.

Two conferences at Berkeley - Berkeley Report from Dr. K.Mikami
MSRI holds a semester program “Microlocal Analysis” in fall 2019. I fortunately attend this program while my stay at University California Berkeley (UCB) via iTHEMS-UCB math young visiting scholar program. There were two conferences on microlocal analysis in the third week of October. From October 14 to 18, there was a conference entitled “Recent Development in Microlocal Analysis”. It consists of 18 talks on various kinds of topics on microlocal analysis by specialists from all over the world. They contain some topics which is very closely related to my research works, such as observability and semiclassical measure. In October 19 and 20, there was a conference entitled “Microlocal Analysis and Spectral Theory: A Conference in Honor of Richard Melrose”. Richard Burt Melrose is an Australian mathematician who is famous for his broad research on microlocal analysis and geometry. The speakers include two fields medalists, Terence Tao and Akshay Venkatesh. Over all, there were around 30 talks(!) in a single week. Though it was a bit tight schedule, all talks were really nice and inspiring. Lastly, it was my great honor to attend these great conferences.

iTHEMS researchers host All-RIKEN VR Workshop
Virtual reality is a useful tool for exploring and presenting 3-D data because your brain is naturally tuned for interpreting the 3-D world. Experiencing the data in 3-D rather than on a 2-D screen takes advantage of these tunings. And, of course, it makes for a very memorable presentation of data, both to scientists and to the public. iTHEMS researchers Gilles Ferrand and Don Warren hosted an all-RIKEN workshop on virtual reality on October 7. This workshop drew nearly 30 people from RIKEN and beyond. Almost everybody studied something other than astrophysics. Most people were not iTHEMS members. Several were not researchers! Attendees learned about the VR project that Gilles and Don have worked on for two years, and got to explore data using VR headsets. The goal of the workshop was to build a community of researchers with a shared interest in VR. And, as Nathan Shammah demonstrated, any time you put scientists in a room together you can get discussion about their work. We hope that continued discussion of VR leads to more discussion of personal research, and maybe even new interdisciplinary projects! If you missed the first workshop, but would like to join Gilles and Don for the second workshop (a day-long, hands-on experience to learn about the VR demo and teach you how to develop software for VR), send Gilles or Don an email.

Short Report of Robotics Workshop held at IIAS in Kyoto
Robotics Workshop organized by RIKEN was held on Sep. 12-13 at a beautiful campus of the International Institute for Advanced Studies (IIAS) in Kyoto. Gilles Ferrand (ABBL/iTHEMS) and Tetsuo Hatsuda (iTHEMS) attended the workshop: Gilles gave a talk on "Virtual Reality and Robotics" and also conducted VR demo during the coffee breaks with Tetsuo as his assistant. All the 35 talks during the two days were "graphically recorded" in real time as the one attached for the Gilles case. (Some illustration company in Kyoto came to do this.) Although each coffee break was short (5-10 min), altogether six people could enjoy the VR of the supernova remnant. It was an interesting experience for us to interact with robotics engineers who have rather different way of thinking from the researchers in basic sciences.

Japan-Israel Workshop on HEA with Roger Blandford
During 18-23 July, a workshop to bring together experts on High Energy Astrophysics from Japan and Israel was held. The first part (18-19 July) was held in RIKEN Wako, while the second part (22-23 July) was held in RIKEN Kobe IIB. The workshop was supported by iTHEMS. This workshop was motivated by 3 things. One was Roger Blandford, a reviewer of iTHEMS AC, was planning to visit RIKEN Wako during 24-26 for the review. Second was Noemie Globus, who is a visitor of Astrophysical Big Bang Lab. (ABBL), was interested in organizing a meeting between Japan & Israel. She worked well as a Co-Chair of the meeting. Third was Hirotaka Ito (Chair, ABBL) has some collaborators in Israel, including Amir Levinson & Asaf Pe'er. We enjoyed lots of excellent talks both from Japan & Israel. Roger Blandford gave a talk on his interpretation of the black hole shadow image by the even horizon telescope (EHT). We had lots of discussions with Israel people, and we agreed to proceed our collaborations on long/short gamma-ray bursts. We received many emails from Israel people that they enjoyed the workshop and their stay in Japan very much, and some of them proposed to have a second meeting in Israel. Hirotaka Ito & Noemie Glogus worked very well as chairs of organizers. Thanks to them & iTHEMS, the meeting was very successful.

ホットトピックReport of the workshop on "Math of Jets"
A workshop on "Math of Jets" co-sponsered by RIMS (Kyoto University) and iTHEMS was held from July 29 to 31 at Kyoto University. Researchers from wide scientific fields, such as, planetary atmosphere, astrophysics, quark-gluon plasmas, and so on gave talks. The common keyword for participants are 'jet' and/or 'hydrodynamics'. Since most of participants use numerical hydordynamic or magnetohydordynamic simulations as a tool for their study, some part of discussions are devoted to introduce numerical technique, numerical difficulties and unresolved problems. We enjoyed getting to know research topics and problems in other research fields. At the workshop banquet, one of participants said as a speech "Recently the borders between countries have not been so high but the borders between scientific field have been getting higher and higher, event if they have common language, for example, 'hydrodynamics' like us. We should continue this kind of workshop. Otherwise, we can not understand each other in near future." The workshop was good opportunity to interact with other fields and we hope we will have next meeting in near future.
