2018-07-02

On June 28, joint innovation seminar between RIKEN iTHEMS and Denso IT lab. was held. After the general introduction to the Denso IT lab. There were two talks from Denso IT lab. (Human-car interface; Machine leaning and computer vision) and two talks from RIKEN iTHEMS (Topology in classical systems; Hadrons in quantum chromodynamics). It turned out that the background of all 4 speakers are theoretical physics. The iTHEMS coffee room was filled with people from both labs. and lively discussions among participants continued until 8pm. This meeting would be a model case where "real" interactions between researchers in academia and industry are made possible.

Hot Topic

Prof. Satoshi Aoki's one day lecture was held on June 26

2018-06-29

On June 26, Professor Satoshi Aoki (Kobe Univ.) gave a series of lectures about "computational algebraic statistics and its applications". His lecture is about application of the Grobner basis to statistic theory. Lecture 1 was an introduction to ideal of polynomial rings and its relation to the Grobner basis. In Lecture 2, he explained Grobner basis in design of experiments. In Lecture 3, he explained Grobner basis in statistical hypothesis with contingency tables. There were more than 30 participants from inside and outside of RIKEN. Background of the participants are mathematics, statistics, physics, biology, information science and medical science. There were many questions from the participants on the mathematical and practical aspects of the Grobner basis, and the lively discussions continued at the time of lunch and coffee break. This lecture turns out to be a model case of having both mathematicians and practitioners together to discuss the power of mathematics and it applications.

Symposium

Supported by iTHEMS

International Symposium on Quantum Fluids and Solids (QFS)

July 25 - 31, 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.

Venue: Ito International Research Center (IIRC), Hongo Campus, The University of Tokyo

Self-introduction: Jason Chang

2018-07-02

I am Jason Chang, a research scientist at iTHEMS. I received my bachelors and PhD in physics from the University of Illinois at Urbana-Champaign. During my PhD, my focus was on calculating the hadronic contributions to flavor physics using lattice quantum chromodynamics (LQCD). Afterwards, I joined the LQCD group at Lawrence Berkeley National Laboratory (LBNL) to understand the contributions of the strong interaction in nuclear matter. My interests have since then also extended to explore the possibility of applying quantum annealing to machine learning techniques, and as led to new collaborations with scientists from condensed matter and quantum information science. I am very happy to join iTHEMS, and as a member who is primarily located at LBNL, I look forward to hosting and working with anyone interested in visiting the Bay Area for both the collaboration opportunities with scientists here, as well as industry experts around this area.
