International Symposium on Mesoscopic Superconductivity

The symposium was held on March 8-10, 2000, at the NTT Atsugi R&D Center in collaboration with New Energy and Industrial Technology Development Organization (NEDO) and The Physical Society of Japan (JPS). Recently, a new field of physics called "Mesoscopic Superconductivity" has emerged. In this field, various unique quantum phenomena, such as Andreev reflection, can be observed. In Andreev reflection, the incident electron is reflected as a hole at the superconductor/normal-conductor (SN) interface. NTT Basic Research Laboratories has led this field, and the symposium aspired to gather the leading scientists and discuss the most recent topics.
Mr. Tetsuo Noguchi, Deputy Director General of New Energy and Industrial Technology Development Organization, and Dr. Sunao Ishihara, Director of NTT Basic research Laboratories, opened the symposium with welcoming remarks. Next, Dr. Hideaki Takayanagi, Executive Manager of NTT Basic research Laboratories, gave a keynote address.
On the 8th, the symposium focused on physics of Andreev reflection. Prof. Alexsander Andreev of Kapitza Institute for Physics Problems, Russia, the discoverer of Andreev reflection, gave a plenary lecture. There were 8 oral and 36 poster presentations.
On the 9th, the symposium focused on quantum phenomena in mesoscopic SN coupled systems, such as superconducting small junctions, excess noise properties in SN systems, and superconductor/semiconductor systems. The symposium was addressed by the leading scientists in this field, Prof. Igor Kulik of Bilkent University, Turkey, and Prof. Tord Claeson of Chalmars University of Technology, Sweden. There were 12 oral presentations.
On the 10th, the symposium focused on quantum computing, such as quantum computing with superconducting junctions and quantum coherence of a qubit. The speakers were the leading scientists in this field, Dr. Yasunobu Nakamura of NEC Fundamental Research Laboratories, and Prof. Johan Mooij of Delft University of Technology, the Netherlands. There were 7 oral presentations.
The participants were 127 people [companies and universities: 88 (overseas: 45, domestic: 43), NTT: 39]. One participant was strongly impressed by the high quality of the presentations. The proceedings will be published in the special issue of Physica C. The symposium was recorded on videotape and the tape has been used for public relations.
