New Paradigm of Few-Baryon System

It is briefly reviewed that the chiral perturbation theory and methods solving the complex few-baryon system. By the Faddeev-Yakubovsky calculations and many successful methods, the four-nucleon bound system is solved very accurately at present. The three-body scattering calculations also have been developing. Many accurate methods applied not only to few-nucleon system but also to exotic baryon systems. The good communication between high quality measurements and these precise calculations pins down strongly requirement for a new paradigm of nuclear force. One of expected scenario is the chiral perturbation theory, which is not made directly from the quantum chromodynamics (QCD), however, it is constrained by the chiral symmetry which the QCD originally posses. The hierarchy of the chiral perturbation theory supports the consistency between the 2-nucleon force and manybody forces, where the study of few-nucleon system beyond 2-nucleon system is important as well as the study of 2-nucleon system because the low-energy constants of which the chiral perturbation Lagrangian consists, commonly appear in all fewnucleon system.

The Mystery of Glasses : Dynamic Heterogeneity and Universality of Ion Dynamics in Ion-Conducting Materials――

Characteristics of mysterious dynamics in ionically conducting glasses are explained based on the results of molecular dynamics simulations. Attention is focused on the universal dynamic response and heterogeneity of dynamics. Ion dynamics in Li_2SiO_3 glass is characterized by van Hove functions, non-Gaussian parameters and analysis of jump motions and explained by the concept of temporal and spatial exponents. Dynamical potential surface of Li ions in the lithium metasilicate (Li_2SiO_3) glass, obtained by the accumulated positions of Li ions during a MD run, has been analyzed by using singularity spectra to show a multi-fractal character. Mixing of localized ion and diffusive ion dynamics is one of the causes of the multi-fractality observed. Single particle motions of Li ions on the surface have been examined by the principal component analysis of the time series (singular spectrum analysis; SSA). Phase-space plots using denoised data obtained by SSA show the deterministic character of the dynamics of ions, localized and diffusive.

Looking for the Origin of the Matter-Antimatter Asymmetry――Recent Results from the Belle Experiment――

Why is our Universe made of matter and not antimatter? It might be explained if the laws that govern matter and antimatter are different. In 1964, matter-antimatter asymmetry was discovered in the weak decays of elementary particles called Kaons. At the KEKB B factory we have discovered CP violations in B meson decays and have thus established the Kobayashi-Maskawa model of CP violation. The present article reviews the history of CP violation, focusing on recent results from the B factories and prospects in this field.

Cosmological Magnetic Field : A Fossil of Density Perturbations in the Early Universe

It is one of the greatest problems in cosmology when and how cosmological magnetic fields are generated. We show that density perturbations in the early universe generate magnetic field by considering an effect which is so tiny that it has been neglected so far. By following the evolution of perturbations numerically we give the spectrum of generated magnetic field and show the possibility that they act as seed fields for galactic magnetic fields.

Doubly Excited Resonances in Molecular Hydrogen――An Outstanding Problem of the Simplest Molecule

Formation and decay of molecular doubly excited resonances is a challenging subject in molecular physics since the Born-Oppenheimer approximation and mean field approximation are not valid. We succeeded in observing the doubly excited resonances in electron-H_2 collisions by means of coincident electronenergy-loss spectroscopy. A newly found doubly excited state 'F' was proposed to substantiate a peak around 26eV. However such state has not yet been obtained theoretically. In order to understand the dynamics of the doubly excited H_2 in more detail we have recently carried out the (γ, 2γ) coincidence experiment on H_2. It has been found that a semiclassical approximation describes well the dynamics of the Q_2^1П_u(1) state of H_2. The origin of the 26eV peak, however, remains an open and tough question.

Ultrafast Relaxation Dynamics Induced by Core Level Excitation in Condensed Systems

We can often see a large atomic displacement induced by an X-ray excitation, even though the excited core electron does not participate in the bonding of materials. Core level excitation has in nature a local character, so that the excited state is strongly coupled with local vibrations. We report the recent studies of the ultrafast relaxation dynamics induced by a core excitation.
