Quantum transport in a normal metal/odd-frequency superconductor junction
Jacob Linder, Takehito Yokoyama, Yukio Tanaka +2
Recent experimental results indicate the possible realization of a bulk odd-frequency superconducting state in the compounds CeCuSi, and CeRhIn. Motivated by this, we p…
Predominant Magnetic States in Hubbard Model on Anisotropic Triangular Lattices
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +1
Using an optimization variational Monte Carlo method, we study the half-filled-band Hubbard model on anisotropic triangular lattices, as a continuation of the preceding study [J. P…
Chirality sensitive effect on surface states in chiral p-wave superconductors
Takehito Yokoyama, Christian Iniotakis, Yukio Tanaka +1
We study the local density of states at the surface of a chiral p-wave superconductor in the presence of a weak magnetic field. As a result, the formation of low-energy Andreev bou…
Theory of pairing symmetry inside the Abrikosov vortex core
Takehito Yokoyama, Yukio Tanaka, Alexander A. Golubov
We show that the Cooper pair wave function at the center of an Abrikosov vortex with vorticity m has different parity with respect to frequency from that in the bulk if m is an odd…
Theory of Fulde-Ferrell-Larkin-Ovchinnikov state of superconductors with and without inversion symmetry: Hubbard model approach
Takehito Yokoyama, Seiichiro Onari, Yukio Tanaka
We study Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state of superconductors with and without inversion symmetry based on the Hubbard model on the square lattice near half-filling, us…
Conductance Spectroscopy of Spin-triplet Superconductors
Yasuhiro Asano, Yukio Tanaka, Alexander A. Golubov +1
We propose a novel experiment to identify the symmetry of superconductivity on the basis of theoretical results for differential conductance of a normal metal connected to a superc…
