My colleagues and I have presented a systematic treatment of a broad area of modern optical physics dealing with electronic coherence and fluctuations in condensed matter. It is a field that has largely developed since the first lasers became available in the 1960s. My research covers various nonlinear optical techniques that are needed for spectroscopic purposes. These are applied to subjects that have not been treated systematically before, such as radiation from sources of different states of coherence, effects of source coherence on the nonlinear spectra and scattering of partially coherent light by electronically resonant population grating. |

Protons, neutrons and mesons that generate nuclear force are called hadrons. One can study the structure and the properties of hadrons by examining various physical phenomena that take place at a scale of 10 to the -15 meters in length and several hundred million electronvolts in energy. I am studying the structure of hadrons in terms of quarks and gluons, and also hadronic reactions that take place in high energy collisions using quantum mechanics, the theory of special relativity, quantum theory of fields etc. |

Is the bird a descendant of the dinosaur? Why can birds fly in the sky? I have found a growth hormone-like material in the pancreatic islets of birds. If there was a growth hormone in the pancreas of the dinosaur, the huge growth of the dinosaur may depend on this pancreatic growth hormone. I am comparing the flight muscle of various kinds of birds using enzymehistochemistry. |

Characterization of Molecules Adsorbed in Nano Space and Development of New Functional Nano Porous Materials
The behavior of molecules in small pores of about 1nm diameter (nanopore) differs from that of free molecules. The low dimensional environment formed by steric limitation of nanopores has often been used as a reaction field for catalysts. I am investigating the behavior of molecules adsorbed in various nano porous materials using spectroscopy, kinetical and thermodynamical methods, and we are working towards the development of new materials with excellent functionality for catalysts and adsorbents. |

Akira Yoshihara
Doctor of Science
My research activities are focused mainly on Brillouin light scattering (BLS) from thermally excited spin waves in magnetic films, ultrathin films, multilayers, and superlattices. Recently I have started a new research project on the BLS study of spin waves from magnetic granular materials. BLS is a standard technique not only for determination of the magnetic constants of magnetic materials but also for the investigation of coupling phenomena, and surface and interface phenomena in film magnetism. Besides these basic interests in film magnetism, magnetic films are also higher potential materials for many industrial applications. For the characterization and further development of new functional magnetic materials, it is essential to determine the magnetic constants of magnetic materials. For this purpose BLS can be the best technique. I and my colleagues are cooperating with many research groups from several universities and research institutes in Japan.
We are also studying the elastic properties of various polymer films and viscoelastic materials as a function of temperature using the BLS technique. |

Systematics and the evolution of flowering plants
More than 1.5 millions species have been known in Earth. These species exhibit diversity in various features such as forms, habits and genes. From such diversity we can find useful information for circumscribing species, reconstructing phylogenetic relationships among species, and making inferences about the evolution of morphological features. My research has focused on systematics and the evolution of flowering plants, especially the legume family. |

Nuclear reaction rates at low energies play a key role in energy generation in stars, in the origin of elements in stellar conditions, and in the early universe. The crucial point is the tunneling process of the nuclear fusion reactions that occurs in association with the motion of atomic electrons or the electron plasma. I have been investigating the influence of electron screening on the tunneling at low energies by using the path-integral and semi-classical approach, which has been developed so far to study other low energy nuclear reactions, i.e. sub-barrier fusion and spontaneous fission of heavy ions. It is theoretically shown that the motion of electrons is not well described by the static adiabatic potential but by the dynamical tunneling theories; this is inconsistent with the recent experimental results of Rolf’s group that the fusion reactions of 2He+d and 3He+d with a gas target show increasing enhancement along with decreasing bombarding energies. |

Light scattering study of soft matter systems
Soft matter physics is one of the branches of condensed matter physics. The term 'softness' originally means mechanical properties of materials. We however give this term a more general definition: keen sensitivity to external force or disturbance. Polymeric materials (solutions, gels, rubbers), liquid crystal, colloidal dispersions are considered to be soft matter systems in our definition. These systems include fairly complex molecules bound by weak interactions with each other, so they have an extremely large internal degree of freedom, which gives rise to complex and rich behavior responding to a very small change in environmental parameters. This is the very reason why soft matter systems pose challenging and curious problems in physics. The properties we are discussing include viscoelasticity, critical phenomena, phase transition and so on. We are mainly studying viscoelastic properties of polymeric materials under two dimensional (2D) confinements. Theoretically the effect of entanglements of polymer chains strongly depends on the dimensionality of the space. We are trying to demonstrate this effect experimentally, measuring the viscoelasticity of 2D polymer solutions spread on a liquid-gas interface. We are developing a new experimental method of light scattering to measure very weak signals from 2D polymer systems. |

In temperate regions, deciduous and evergreen broad-leaved trees show clear and characteristic seasonal growth. I am investigating such seasonal properties in conjunction with the phonological process of shoots, annual thickening growth and diurnal diameter changes of stem and root. Water relations in trees are essential for all these properties. Thus, the developmental processes of wood structure and vessel networks are also areas for study, and they are closely related to the ascent of sap in trees. These analytical studies correspond to, and are widely expanded from, investigation of water relations among root, stem and leaf. Such properties are closely related to, and/or strictly controlled by, atmospheric phenomena, forest dynamics and agroforestry systems. |

Chiral compounds (one of two enantiomers which are mirror images of each other) are important for the development of drugs, agricultural chemicals, ferroelectric liquid crystals, and such. A mixture of two enantiomers (racemate) is synthesized by general methods, because they have the same physical and chemical properties, with the exception of optical rotation. I am researching methods to yield chiral compounds, asymmetric syntheses and optical resolutions. |
