Searching for the Higgs Boson Particle-Latest results of the LHC experiment

On December 13, the European Organization for Nuclear Research (CERN) attracted great attention when it announced its latest interim results. This organization has been running experiments such as the search for the Higgs boson particle, which is the source of mass. The experiment has been carried out using the Large Hadron Collider (LHC) by two international research groups. One group is the ATLAS Experiment Team, mainly composed of members from Japan, the U.S. and Europe. The other is the CMS Experiment Team, composed of members from U.S. and Europe. Associate Professor Kohei Yorita of the Waseda Research Institute for Science and Engineering is participating in this experiment as one member of the ATLAS Japan Group that consists of 15 organizations in Japan, including the International Center for Elementary Particle Physics (ICEPP) and the High Energy Accelerator Research Organization (KEK).

Team led by Associate Professor Takahiro Shinada, et al. of the Waseda Institute for Advanced Study
Developing a quantum device with controlled single dopant atom

An international joint research team succeeded in controlling the dopant atom within the transistor used in semiconductor integrated circuits and observing the phenomenon of quantum transport. The research team included Associate Professor Takahiro Shinada (Waseda Institute for Advanced Study), Masahiro Hori, a Doctoral Student in the Graduate School of Science and Engineering, and Dr. Enrico Prati from the National Research Council of Italy.

Normally, the dopant has been added in order to set the threshold voltage (on/off voltage) of the transistor. However, for extremely miniature transistors, there was the problem of variation in the threshold voltage due to random distribution of the dopant. Control of this variation was a research theme. Associate Professor Shinada and other researchers controlled each dopant within the transistor and created a one-dimensional array. As a result, they succeeded in observing the phenomenon of quantum transport mediated by a single dopant.

This research heightens the realism of a single dopant atomic device and creates momentum for the development of devices based on new principles.

Symposium on Short-, Mid- and Long-Term Prospects for Energy Problems

The 2nd Short-, Mid- and Long-Term Prospects for Energy Problems symposium series was held at Nishi-Waseda Campus on December 19th. The theme of the symposium was "Fusion of the Construction of Ultra-energy Efficient Smart Communities and Smart Houses with Electricity and Information." After a greeting by Professor Yoshihide Nakagawa, Director of Waseda Research Institute for Science and Engineering, lectures were given by Professor Yasuhiro Hayashi, Professor Shinichi Tanabe, Professor Masafumi Katsuta and Associate Professor Hiroto Takaguchi from the Faculty of Science and Engineering. The professors lectured on their research themes including the use of thermal energy, energy resources and renewable energy (photograph). Approximately 250 members of the general public and students listened intently to the lectures.

The 1st symposium was held in July 2011 in order to address the theme of power crisis. In the future, these symposiums are scheduled to address issues relating not only to power issues, but also thermal energy utilization, energy resources and renewable energy. The plan is to deepen discussions from various viewpoints.
