Hadronic Molecular States with K^^- Meson in Chiral Dynamics

Among self-bound systems by strong interaction, hadronic molecular systems which consist of hadrons as dynamical degrees of freedom are discussed from the viewpoint of chiral dynamics. We conclude that the antikaon and nucleon generate the Λ(1405) resonance as a quasi-bound state. This fact leads to various interesting phenomena in few-body systems with antikaons. On the other hand, the antikaon is one of the Nambu-Goldstone bosons associated with the spontaneous breaking of chiral SU(3)_R × SU(3)_L symmetry of Quantum Chromodynamics. Here we briefly explain the chiral unitary model, which is a powerful tool to describe hadronic resonances with respecting the symmetries in QCD, and review the physics of the Λ(1405) resonance and the few-body systems with antikaons as the hadronic molecular states.

Non-Equilibrium Physics in Strongly Correlated System

We give a review on correlated systems far from equilibrium. There is a rapid development in the field which stems from both photo-induced phase transitions in strongly correlated electron systems and from non-equilibrium dynamics in cold atoms in optical lattices. We explain how ideas developed in non-linear quantum field theory such as the Schwinger mechanism in QED are being extended to many-body systems in the condensed matter version of "strong field physics".

Canonical-Basis Time-Dependent Mean-Field Theory and Linear Response in Superfluid Nuclei

The superconducting in metal is a quantum phenomenon that is realized by the condensation of the electron pairs at low temperature. In heavy nuclei, protons and neutrons also exhibit properties of the superfluidity caused by their pair condensation. The numerical simulation of reactions for such superfluid nuclei was considered to be impractical, because of its enormous required computational resources. Recently, we have developed a new approach, "canonical-basis time-dependent mean-field theory", which succeeds to significantly reduce the computational cost. Using this new method, it is expected to reveal complex reaction mechanism of superfluid nuclei.

Low-Dimensional Electron Systems Formed from Metal Thin Films and Stacking Faults

Metal thin films grown on semiconductor substrates in a layer-by-layer fashion possess quantum well states and Shockley surface states, both of which are typical two-dimensional electronics states. Recently, we have successfully fabricated metal thin films with stacking-fault superlattices using a surface reconstruction as a growth template. Later on, we have also found that their electronic states feature a high anisotropy or one-dimensionality. In the present article, we introduce this kind of new low-dimensional electron systems.

High-Energy-Density Science with Pulse-Power Energy Drivers

Recent progress of pulse-power based drivers has enabled us to make well-defined extreme conditions in laboratories with low cost and good reproducibility. We show that dense plasmas produced with a pulse power based energy driver and/or intense ion beams are capable of laboratory studies on the conductivity and the equation of state of matters in warm-dense-state. A possible method to make an extreme condition for the study on astrophysical strong shock waves is also discussed, together with consideration on the similarity criterion.

Universal Thermodynamics of a Unitary Fermi Gas

Inter-particle interaction reaches maximum allowed by quantum mechanics at the unitarity limit. At the limit, thermodynamic properties of the system depend only on the temperature and density, but does not depend on any material-specific parameters. In this article, we describe the experimental determination of universal thermodynamics of an ultracold Fermi gas at the unitarity limit.
