Second Workshop on Fundamentals in Density Functional Theory (DFT2024)

February 20 (Tue) - 22 (Thu), 2024

The density functional theory (DFT) is one of the powerful methods to solve quantum many-body problems, which, in principle, gives the exact energy and density of the ground state. The accuracy of DFT is, in practice, determined by the accuracy of an energy density functional (EDF) since the exact EDF is still unknown. Currently, DFT has been used in many communities, including nuclear physics, quantum chemistry, and condensed matter physics, while the fundamental study of DFT, such as the first principle derivations of an accurate EDF and methods to calculate many observables from obtained densities and excited states. However, there has been little opportunity to have interdisciplinary communication. On December 2022, we had the first workshop on this series (DFT2022) at Yukawa Institute for Theoretical Physics, Kyoto University, and several interdisiplinary discussions and collaborationd were started. To share such progresses and extend collaborations, we organize the second workshop. In this workshop, the current status and issues of each discipline will be shared towards solving these problems by meeting together among researchers in mathematics, nuclear physics, quantum chemistry, and condensed matter physics. This workshop mainly comprises lectures/seminars on cutting-edge topics and discussion, while a half-day session composed of contributed talks is also planned. This workshop is partially supported by iTHEMS-phys Study Group. This workshop is a part of the RIKEN Symposium Series. The detailed information can be found in the workshop website.

Can social issues be solved by mathematical science!? - Mathematical Research in Corporations

February 3 (Sat) at 13:00 - 17:00, 2024

Continuing from the previous fiscal year, we will be hosting a symposium exploring the potential of solving societal issues through mathematical science research. In the past two years, the themes were "Attempts and Challenges" and "Connecting Corporate Issues and Mathematical Sciences." This year, we will focus on concrete examples under the title "Mathematical Research in Corporations" with the aim of introducing activities utilizing mathematics in the corporate sector. Currently, we are inviting speakers with diverse backgrounds, including researchers actively engaged in mathematical activities within corporations or those who have transitioned from corporate mathematical research to academic settings. We are particularly interested in learning about the experiences of individuals who have used mathematics in corporate settings. Additionally, there has been a growing trend in connecting activities of graduate students in mathematics with corporate endeavors. By sharing such initiatives with participants, we plan to conduct a panel session for exchanging opinions on the role of mathematical science in addressing societal issues through corporate collaboration in the future. We sincerely look forward to the active participation of corporate researchers and mathematicians who have an interest in these activities.

Can social issues be solved by mathematical science!? - Connecting Corporate Issues and Mathematical Sciences -

January 7 (Sat) at 13:00 - 17:00, 2023

Continuing from last year, we will hold a symposium to explore the possibility of solving social issues through mathematical research. Last year, under the theme of "Social Implementation of Mathematical Research!? - Attempts and Challenges -", we held talks by mathematical scientists working on mathematical problems extracted from corporate issues, and saw that efforts to address issues of interest at the individual researcher level are becoming more active. This year, under the broader theme of "Connecting" mathematical scientists and companies, we will introduce not only researchers who are strongly promoting joint research with companies, but also activities of companies who are collaborating with mathematical scientists from the standpoint of companies. We would like to organize a panel session to share with the participants not only the results of their activities but also the difficulties of the collaboration and the exchange of opinions on how to solve the problems. We are sincerely looking forward to the active participation of corporate researchers and mathematical scientists who are interested in such activities.

In recent years, the importance of mathematical sciences has been increasingly recognized in various fields, as exemplified by the rapid progress of AI technology and the development of DX (Digital Transformation) in companies. In academia, research centers have been established in fields such as space, materials, life, and medicine, where experts in the mathematical sciences play an important role in research activities in their respective fields. At the same time, the universality of mathematics and the quantitative and predictive nature of data analysis are also being considered useful in industry, and some companies are actively using mathematical science in their own business. Some companies are actively utilizing mathematical science in their business. In this symposium, researchers who are conducting research with the mission of returning research using mathematical science to society and implementing it will gather to discuss, based on the results of their cutting-edge research, "Can social issues be solved with mathematical science? -Attempts and Challenges" and discuss the role of mathematical science in society.

International Symposium on Quantum Fluids and Solids (QFS)

July 25 (Wed) - 31 (Tue), 2018

The International Symposium on Quantum Fluids and Solids (QFS) will be held at Ito International Research Center (IIRC) on Hongo campus of the University of Tokyo, Japan, from July 25 through 31, 2018. One of the sponsors of this conference is iTHEMS. The QFS series started forty-three years ago making it one of the oldest series of international conferences in the field of low temperature physics. It has historically been focusing on physics of liquid and solid helium and hydrogen. But in this century its scope is expanding widely from laser cooled cold atoms to topological matters. At QFS2018 in Tokyo, this trend will be continued and with even more interdisciplinary aspects emphasized between the traditional subjects and those in broader physical systems.

Interdisciplinary symposium on modern density functional theory

June 19 (Mon) - 23 (Fri), 2017

Density functional theory (DFT) is one of the most widely used methods for quantum many-body problems in condensed matter, nuclear physics, and quantum chemistry. Although we share similar theoretical frameworks and computational techniques, we sometimes use quite different languages, which sets a certain barrier for efficient interdisciplinary collaborations on modern DFT, in particular, that powered by High Performance Computing Infrastructure (HPCI). The key idea of this symposium is to have intensive interdisciplinary discussions and to initiate a new collaboration platform, in particular, by introducing the basic methodology and highlighting the latest hot topics in the fields condensed matter, nuclear physics, and quantum chemistry. iTHEMS-AICS-RNC-U.Tokyo joint symposium
