Abstract

We would like to thank Professor H. Kosaka for stimulating discussions and continual encouragements. We appreciate very much the financial supports from the CREST project of the Japan Science and Technology Agency, from the SCOPE program of the Ministry of Internal Affairs and Communications, and from the Ministry of Education, Culture, Sports, Science and Technology, Japan. The numerical calculation in this work has been done using the facilities of the Supercomputer Center, Institute for Solid State Physics, University of Tokyo.

Tonomura FIRST International Symposium on Electron Microscopy and Gauge Fields

Yoshimasa A. Ono

On May 9 and May 10, 2012. Tonomura FIRST International Symposium on “Electron Microscopy and Gauge Fields” was held in downtown Tokyo hosted by Japan Science and Technology Agency together with Hitachi, Ltd., RIKEN, Ministry of Education, Culture, Sports, Science and Technology, OIST, The Asahi Shimbun, Nikkei Inc. and Nikkei Science Inc. Here FIRST stands for “Funding program for world-leading innovative research and development on science and technology”. In 2010 as principal investigator Dr. Akira Tonomura was awarded this Japanese-government-funded project aiming at developing a 1.2 MV “holography electron microscope” which is capable of observing quantum phenomena in the microscopic world. The symposium was also intended to celebrate his 70th birthday, but on May 2, just a week before the opening of the symposium, Tonomura passed away during the course of a medical treatment on pancreatic cancer. Consequently, what had been planned to be a grand meeting with many of his scientific friends from all over the world, then turned as a memorial conference.
