From the Office

The office of iTHES assistant, Ms.Chikako Oota is situated at the first floor of the main research building, room # 159. The extension number is 3185. She will be at the office from 10 a.m. to 16 p.m. except on Wednesday.

From the director


Wecome to iTHES ! It is our great pleasure to start the weekly Newsletter. iTHES (Interdisciplinary Theoretical Science) Research Group is a newly founded framework that integrates the research activities in theoretical science at RIKEN. It promotes interdisciplinary collaborations among theorists in fundamental physics, material science and biological science. Also, iTHES aims to intertwine young theorists in various fields and disciplines and to create an ideal environment for developing new ideas.
The organization of the iTHES Research Group can be found in the web page:
and the full list of current iTHES members can be seen from
We will have more than ten iTHES Researchers (research scientists and postdoctoral fellows) every year. To enhance the mutual interactions among the scientists in various fields, we organize iTHES Colloquiums and iTHES Seminars. Furthermore, we promote interdisciplinary workshops, conferences and outreach activities. Also we support short term and long term visitors.
Details of the iTHES activities are posted in the web page:
http://ithes.riken.jp/ .
The aim of the weekly iTHES Newsletter is to inform the updated information to the iTHES members and the scientists interested in iTHES activities. We do hope that the iTHES Research Group becomes a seed for interdisciplinary collaborations and for new scientific developments.

Norihiro Iizuka

As a theoretical physicist, my research interests are literary everything in nature. Ultimately I would like to understand everything from very fundamental viewpoint. The developments of modern physics enable us to understand amazingly many things in nature between cosmic-scale large distances to subatomic-scale short distances. However, there are yet several unsolved problems in modern physics, and I am especially interested in following two unsolved problems: ? Understanding quantum properties of gravity and space-time ? Understanding strongly coupled quantum field theories In order to understand these, I am working on string theory, a candidate for a theory of everything. I am especially working on the ``gauge/gravity duality'', a new principle which I believe to be one of the greatest achievement in modern physics. Understanding these will help us to understand the `Big Bang singularities', and this should help us to understand fundamental questions such as “where does our universe come from?”
