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.
