Fukuyama, Hidetoshi, Fuseya, Yuki, Kobayashi, Akito
Features of electronic currents in solids are truly diverse depending on circumstances, e.g. non-equilibrium transport currents leading to dissipation and persistent currents flowing in equilibrium....
Unscreening Effect on Fe-Pnictide Superconductor (2008)
Fuseya, Yuki, Kariyado, Toshikaze, Ogata, Masao
We study a microscopic mechanism of Fe-pnictide superconductor, considering the screening effects of Coulomb interaction in addition to the conventional spin-fluctuation mechanism. It is shown that,...
Quantum Monte Carlo Study of the Quasi-One-Dimensional Superconductivity (2008)
Aonuma, Tohru, Fuseya, Yuki, Ogata, Masao
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-salts. We focus on the...
We study the triangular $t$-$J$ model with multiple spin exchange interactions using exact diagonalization of small clusters, as a model of monolayer liquid $^3$He. A phase where the energy spectrum...
Response functions for spin-density-wave (SDW) and d-wave singlet superconductivity ($d$SC) in quasi-one-dimensional (Q1D) electron systems are calculated by a renormalization group technique. It is...
Interband Effects of Magnetic Field on Hall Effects for Dirac Electrons in Bismuth (2008)
Fuseya, Yuki, Ogata, Masao, Fukuyama, Hidetoshi
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 $\sigma_{xy}$...
Fuseya, Yuki, Tsuchiizu, Masahisa, Suzumura, Yoshikazu, Bourbonnais, Claude
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) systems to Q-1D systems....
Fuseya, Yuki, Tsuchiizu, Masahisa, Suzumura, Yoshikazu, Bourbonnais, Claude
The temperature dependence of the magnetic susceptibility, \chi (T), is investigated for one-dimensional interacting electron systems at quarter-filling within the Kadanoff-Wilson...
