| Research Abstract |
The object of our group is to study quantum mechanical interactions between matter and light in a simple system and to provide support for other groups working with micro-spheres and semiconductors. The technique by Ohtsu et al on the optical fiber tips contributed to the progress of the works that use SNOM technique. Theoretical achievements of our group include new proposal of quantum computer elements, Quantum Zeno effect and an extensive analysis of near field optical fields. Kitagawa proposed a quantum computer elements that uses nuclear magnetic resonance of organic molecules and designed the method to extract the computed results by using parity gates. Kitano discussed the relation between the quantum Zeno effeet and adiabatic evolution of a auantum system. Cho et al discussed in detail near field optical response of materials from the first principle. They gave a generalized formulae that can be applied to the soliton theory, dynamic diffration of X-ray and photonic band theory. The theory contributed to the theoretical analysis of experimental works of other groups. On the experimental side, Inoue et al produced for the first time a two-dimensional photonic band crystal in one micron wavelength region and observed new laser action with a doped crystal. They developed also three dimensional photonic band crystals in microwave region with silicon crystals. Shimizu et al worked with laser-cooled metastable neon atoms. They studied dynamics of optical lattices, quantum statistical characteristics of ultra-cold collisions and two atom correlation spectra. They developed also microwave lens for neutral atomic beam and atom holography.
