6th NTT-BRL School

   The sixth NTT Basic Research Laboratories (BRL) School was held on November 24-26, 2013 at our NTT Atsugi R&D Center. The aim of the school was to foster young researchers in the nano and quantum science fields and to promote the international visibility of NTT BRL. This year the theme of the school was "Nano and Quantum Science: Driving Tomorrow’s Technology", closely related to ongoing research within NTT BRL. Prestigious professors and researchers were invited as the school lecturers. We accepted thirty-five students, mainly Ph. D students, from fourteen countries.
   On the first day, Prof. John Clarke (University of California, Berkeley, U.S.A.) presented lectures entitled "Theory, practice and applications of Superconducting Quantum Interference Devices (SQUIDs)". He also gave lectures on the second day that covered applications ranging from cosmology to medicine using SQUID femtoscience. On the afternoon of the first day, after the director of NTT BRL, Dr. Tetsuomi Sogawa, provided an introduction of NTT Laboratories, while the three senior distinguished researchers of NTT BRL gave lectures on "Micro/nanomechanical systems using compound semiconductor heterostructures" by Dr. Hiroshi Yamaguchi, "Topologically protected quantum effects in solid state" by Dr. Koji Muraki, and "Nanophotonics toward the smallest energy consumption" by Dr. Masaya Notomi. On the second and third day, Prof. Oliver Schmidt (Institute Director, IFW Dresden, Germany) gave two lectures entitled "Quantum dots: From growth to quantum device" and "Shaping nanomembranes into a new nanoworld". After the lecture of the second day, we conducted a lab tour to show our research facilities and introduce recent research activities at NTT BRL. Then we went on an excursion to Mt. Ohyama belonging to Tanzawa mountain range which is close to the NTT Atsugi R&D Center. The participants enjoyed foliage that was lighting up and tofu dishes at a Japanese traditional restaurant. On the third day, Prof. Jonathan Finley (Walter Schottky Institute, Germany) gave a lecture on "Optically probing charge and spin dynamics in single and coupled quantum dots". After the lecture, all participants attended ISNTT (an international conference on nanoscale transport and technology) hosted by NTT BRL. As part of this, the students gave poster presentations regarding their university research. All students, lecturers, and NTT BRL researchers had excellent time exchanging information on current research topics in various fields. In the joint party of BRL School and ISNTT, "Best Poster Prizes" were awarded to three students who gave noteworthy poster presentations. The students got the opportunity to discuss high-quality research and build human network and friendships within this school. NTT BRL will continue to provide these occasions to support young researchers and to establish research collaborations in the fields of nano and quantum science.
