JOURNAL FREE ACCESSForty years ago, I was trying to solve the problem of the resistance minimum in dilute magnetic alloys. In this note, I shall describe experimental facts that played an essential role in solving the problem and difficulties involved in the problem that embarrassed theoretical people at that time. I shall then mention how the difficulties were overcome.View full abstractDownload PDF (545K) -

JOURNAL FREE ACCESSIn this review we consider the localized magnetic moment in magnetic dilute alloy systems. Anderson explained the appearance of magnetic moment by using Anderson-Hamiltonian on the basis of the Hartree-Fock approximation. However, by the Kondo theory it is shown that there exists a logarithmic divergent term of temperature T in the electrical resistivity. Thus, the magnetic solution is not stable and the localized spin composes the singlet ground state to solve the degeneracy due to the doublet. As the result, we have always a nonmagnetic Fermi liquid state as the ground state. In the ground state, physical quantities are analytic function of the Coulomb repulsion U.View full abstractDownload PDF (1008K) -

JOURNAL FREE ACCESSBoth Kondo effect and superconductivity are remarkable phenomena which conduction electrons in metals show at low temperatures. In metals containing magnetic impurities, the antiferromagnetic coupling between the impurity spin and the conduction electrons leads to a formation of spin singlet due to the Kondo effect, whereas in superconductors conduction electrons form Cooper pairs (spin singlet in most cases). Therefore superconductivity competes with the Kondo effect. The competition can be described with the ratio of the Kondo temperature TK to the superconducting transition temperature Tc. In the present article the relation between the Kondo effect and superconductivity is reviewed by taking up two problems: (1) electronic states of magnetic impurities in superconductors and (2) the influence of the Kondo effect on Josephson coupling beween two superconductors, which are connected via quantum dot.View full abstractDownload PDF (1062K) -

JOURNAL FREE ACCESSThe f electrons of cerium and uranium compounds are localized at the atomic sites and the indirect f-f interaction is mediated by the spin polarization of the conduction electrons and enhances the long-range magnetic order, which is known as the RKKY interaction. On the other hand, the Kondo effect quenches the magnetic moments of the localized f electrons by the spin polarization of the conduction electrons. The competition between the RKKY interaction and the Kondo effect forms the heavy fermions at low temperatures. The localized-f electronic state is thus changed into an f-derived band with a flat dispersion, possessing an extremely large effective mass. These conduction electrons condense into a new superconducting state, which is highly different from the conventional BCS type. It is also noted that in these compounds the electronic states are tuned by magnetic fields and pressures because the characteristic temperatures are low.View full abstractDownload PDF (1249K) -

JOURNAL FREE ACCESSThe Kondo effect in quantum dots arises from singlet coupling of a spin half electron localized in a quantum dot to Fermi electrons in the contact leads. This quantum dot then plays a role of a magnetic impurity. In addition, for quantum dots various important parameters associated with the Kondo effect such as spin configuration, state degeneracy and the way of coupling to contact leads are all tunable, and this enables novel approaches for the Kondo physics. In this article we describe such examples, which are observations of the unitary limit Kondo effect and enhancement of the Kondo effect by state degeneracy.View full abstractDownload PDF (1379K) -

JOURNAL FREE ACCESSWe investigate alpha cluster condensation in light 4N nuclei (4N is the number of nucleons) by a new α-cluster wave function which can describe Bose-Einstein condensation from a full microscopic framework. We conjecture a possible existence of α condensation near the Nα particle threshold energy. In other words, we can regard it as an "α gas-like state."View full abstractDownload PDF (907K) -

JOURNAL FREE ACCESSThe effects of the nuclear deformation and nuclear shell structure on the heavy-ion fusion reaction are investigated. Evaporation residues for various reaction systems were measured using a recoil mass separator near Coulomb barrier. It is found that the fusion probability is nearly equal to one at the side collision and almost zero at the tip collision between spherical projectile and deformed target. It is also found that the fusion probability strongly correlates with the sum of the nuclear shell energies of projectile and target nuclei, i.e., it increases as the sum of the shell energy decreases. We emphasize the importance of these effects in the synthesis of superheavy element.View full abstractDownload PDF (1142K) -

JOURNAL FREE ACCESSIn an effort to understand "rafts" in biological membranes, we propose phenomenological models for saturated and unsaturated lipid mixtures, and lipid plus cholesterol mixtures. We consider simple couplings between the local composition and internal membrane structure, and their influence on transitions between liquid and gel membrane phases. Assuming that the gel transition temperature of the saturated lipid is shifted by the presence of the unsaturated lipid, and that cholesterol acts as an external field on the chain melting transition, a variety of phase diagrams are obtained. Our results also apply to regions in the ternary phase diagram of lipid/lipid/cholesterol systems.View full abstractDownload PDF (978K) -
