Neutron Life from Supercomputer Simulations

2018-06-05

Jason Chang (iTHEMS/LBNL) and his colleagues have enlisted powerful supercomputers to calculate a quantity known as the "nucleon axial coupling," – which is central to our understanding of a neutron’s lifetime – with an unprecedented precision. Their method offers a clear path to further improvements that may help to resolve the experimental discrepancy of the lifetime of neutrons as well as to learn about as-yet undiscovered physics. The paper was published was published online May 30 in the journal Nature.

Math Lecture

Computational Algebraic Statistics and its Applications

June 26 at 10:00 - 16:30, 2018

Prof. Satoshi Aoki (Professor, Department of Mathematics, Kobe University)

Lecture 1 (10:00-11:30)
An introduction of Groebner bases of polynomial rings

Lecture 2 (13:00-14:30)
Groebner bases theory in design of experiments

Lecture 3 (15:00-16:30)
Groebner bases theory in sampling problems of contingency tables

This introductory lecture is about statistical theory from the point of view of the computational algebraic statistics, in particular the applications of Groebner bases. The statistical theory is a fundamental tool in natural science, social science and humanities, and the Groebner basis is a topic related to multi-variable polynomials. The Lecture will start from an introduction to the Groebner basis which would have wide applications in mathematics, physics, biology, chemistry, engineering, information science and computer science. Therefore, we welcome scientists in any field who are interested in this subject.

The event official language is Japanese (slides and writing are in English).

Self-introduction: Tomoki Ozawa

2018-06-04

I am Tomoki Ozawa, a senior research scientist at iTHEMS. I am originally from Japan. I finished my PhD in the University of Illinois at Urbana-Champaign in the US, and then spent five years as a postdoc at the BEC Center (Bose-Einstein Condensation Center) at the University of Trento in Italy. Then, after spending three months in Brussels, Belgium, I came back to Japan and joined RIKEN iTHEMS this April. My main research interest is in the intersection between condensed matter theory and AMO (Atomic, Molecuar and Optics) theory. In particular, I have been working on many-body and topological physics of ultracold atomic gases and photonics. My style of research is to try to understand target systems in as simple way as possible; this sounds rather trivial, but it often leads to something unexpected in the end. In iTHEMS, I hope to collaborate with people from various backgrounds and start something exciting together.
