Unscreening Effect on Fe-Pnictide Superconductor
Yuki Fuseya, Toshikaze Kariyado, Masao Ogata
We study a microscopic mechanism of Fe-pnictide superconductor, considering the screening effects of Coulomb interaction in addition to the conventional spin-fluctuation mechanism.…
Quantum Monte Carlo Study of the Quasi-One-Dimensional Superconductivity
Tohru Aonuma, Yuki Fuseya, Masao Ogata
We report on the result of quantum Monte Carlo simulation of quasi-one-dimensional electron systems at 1/4-filling, considering organic superconductors such as TMTSF- and TMTTF-sal…
Increase of Superconducting Correlation due to Dimensionality Change in Quasi-One-Dimensional Conductors
Yuki Fuseya, Masao Ogata
Response functions for spin-density-wave (SDW) and d-wave singlet superconductivity (SC) in quasi-one-dimensional (Q1D) electron systems are calculated by a renormalization grou…
Phase Diagram of the Triangular t-J Model with Multiple Spin Exchange in the Doped-Mott Region
Yuki Fuseya, Masao Ogata
We study the triangular - model with multiple spin exchange interactions using exact diagonalization of small clusters, as a model of monolayer liquid He. A phase where t…
Interband Effects of Magnetic Field on Hall Effects for Dirac Electrons in Bismuth
Yuki Fuseya, Masao Ogata, Hidetoshi Fukuyama
Hall effects are investigated for three-dimensional Dirac electrons as a model of bismuth alloys. It is found that there is unconventional contributions to the Hall conductivity $σ…
Role of Interchain Hopping in the Magnetic Susceptibility of Quasi-One-Dimensional Electron Systems
Yuki Fuseya, Masahisa Tsuchiizu, Yoshikazu Suzumura +1
The role of interchain hopping in quasi-one-dimensional (Q-1D) electron systems is investigated by extending the Kadanoff-Wilson renormalization group of one-dimensional (1D) syste…
