Topological aspects of matter have been extensively studied for materials with strong spin-orbit interaction, inspired by the seminal prediction of the topological insulator by Kane and Mele. Although the initial prediction ignored the electron correlation effects, the role of strong electron correlation in the topological properties of materials has been the subject of subsequent wide range of studies particularly for transition-metal as well as rare-earth compounds. The studies include those on the possibility of the topological insulators induced solely by the electron correlation effects. Among others, since the electron correlation and the spin orbit interaction compete, iridium oxides have been extensively studied. Sr_2IrO_4 isostructural to the copper oxide superconductors, R_2Ir_2O_7, which was predicted to show the Weyl semimetal and topological insulator characterized by the domain wall conduction in the magnetic ordered phase, and Na_2IrO_3 proposed as a candidate of Kitaev spin liquid are examples of hot topics for searching rich physics. We review recent studies on emergent phenomena and concepts generated by the interplay of spin-orbit interaction and electron correlation.

Exactly Solvable Quantum Mechanics and Orthogonal Polynomials

We review recent developments of exactly solvable quantum mechanical systems and orthogonal polynomials. The first topic is a natural construction of creation and annihilation operators, which are obtained from the Heisenberg solution of the sinusoidal coordinate satisfying the closure relation. The second topic is a new kind of orthogonal polynomials: exceptional orthogonal polynomials, multi-indexed orthogonal polynomials. They form a complete set of the weighted Hilbert space in spite of the fact that they have missing degrees. Various multi-indexed orthogonal polynomials have been obtained from the study of exactly solvable quantum mechanical systems.

Superconducting Surface Reconstructions : Experimental Demonstration and Observation of Josephson Vortices(Research)

Several kinds of surface reconstructions with metal adatoms on semiconductor surfaces have been recently found to exhibit superconductivity at low temperatures. In this article, superconductivity of the Si(111)-(√<7>×√<3>)-In surface reconstruction is described based on electron transport measurement and scanning tunneling microscopy studies. The former clarifies the emergence of a zero-resistance state and the temperature dependence of critical supercurrent density, while the latter reveals Josephson vortices at surface atomic steps.
