    The Kondo effect is a prototypical example where rich and sometimes surprising new physics emerges from the effects of many-body interactions. Two major streams in condensed matter physics which originate from the Kondo effect are the heavy electron systems and the transport phenomena through quantum dots. In this article the present status and future directions of the two research subjects are discussed from my personal point of view.

    A multilayer alternately stacked with several atomic layers of a ferromagnetic metal and those of a normal metal shows a drastic decrease in its electrical resistance in an applied magnetic field. This discovery in 1988, the giant magnetoresistance (GMR), has developed a new nanotechnology, the so-called spin-electronics (spintronics), offering a variety of issues which involve in magnetism and electrical conduction. Tunnel magnetoresistance (TMR) observed in a tunnel junction, which sandwiches in a few atomic layers of an insulator between ferromagnetic metals, attracts much attention these days both in fundamental and applied levels. Currently this stream leads to understandings of physical phenomena emerging from interactions between charge current and spin current in nanoscale materials.

    Thin carbon foils are extensively used not only for targets and their backing foils in the field of fundamental and experimental physics, but also for stripper foils in high intensity accelerators. We have succeeded in fabricating long-lived boron mixed carbon stripper foils for high-power accelerators. Foils of 10-700μg/cm^2 thick were made by a controlled AC/DC arc-discharge method. The lifetime of the foils was tested with three kinds of beams of 3.2MeV Ne^+ DC ion from a Van de Graaff accelerator, 650keV H^- DC ion from a Cockcroft-Walton accelerator, and 800-MeV, pulsed H^- ion and proton beams in the proton storage ring at the Los Alamos National Laboratory in USA. The 3μA, 3.2MeV, Ne^+ beam deposited a significant energy of about 80W/(300μg/cm^2) which nearly corresponded to the effect of the 400-MeV proton beam of J-PARC. The maximum lifetime was found to be extremely long; 100 and 360 times longer than those of diamond and commercially available carbon foils. Also, the foils were free from any shrinkage during irradiation, and showed an extremely low thickness reduction, even at a high temperature of 1,800K.

    A high-temperature and high-density state will be produced in ultra-relativistic nucleus-nucleus collisions. Just after the collision, the created system is in a non-equilibrium plasma state of quarks and gluons. Dynamics of this non-Abelian plasma can be described by Quantum Chromo-Dynamics. In this article, recent progress on the non-Abelian plasma is reviewed focusing on the instabilities in gauge theories.

    Recent theoretical studies revealed that "magnetic frustration" in magnetic compounds, driven by competing spin interactions, can destabilize local spin ordering, instead giving rise to formation of a spin nematic state. Though spins do not show any vector order, spin degrees of freedom on each bond behave as a director (headless arrow) showing a directional order, which is similar to nematic order in liquid crystals. It was found that the spin nematic phase often appears proximity to the ferromagnetic phase boundary.

    The effects of adding antagonistic salt composed from hydrophilic cation and hydrophobic anion in a mixture of water and 3 methylpyridine are investigated by opitcal microscope and small-angle neutron scattering. We have observed that nanometer-scale structures are induced by the solvation effect. These evidences indicate that pairs of ions of antagonistic salt behave as surfactant molecules.
