Interplay between quantum criticality and geometrical frustration in Fe3Mo3N with stella quadrangula lattice
Takeshi Waki, Shinsuke Terazawa, Teruo Yamazaki +7
In the eta-carbide-type correlated-electron metal Fe3Mo3N, ferromagnetism is abruptly induced from a nonmagnetic non-Fermi-liquid ground state either when a magnetic field (~14 T)…
Drude Weight of the Two-Dimensional Hubbard Model -- Reexamination of Finite-Size Effect in Exact Diagonalization Study --
Hiroki Nakano, Yoshinori Takahashi, Masatoshi Imada
The Drude weight of the Hubbard model on the two-dimensional square lattice is studied by the exact diagonalizations applied to clusters up to 20 sites. We carefully examine finite…
Pseudogap Induced Antiferromagnetic Spin Correlation in High-Temperature Superconductors
Toru Sakai, Yoshinori Takahashi
The pseudogap phenomena observed on cuprate high temperature superconductors are investigated based on the exact diagonalization method on the finite cluster t-J model. The results…
Pseudo-gap behavior in dynamical properties of high-Tc cuprates
Toru Sakai, Yoshinori Takahashi
Dynamical properties of 2D antiferromagnets with hole doping are investigated to see the effects of short range local magnetic order on the temperature dependence of the dynamical…
