Conductance renormalization and conductivity of a multi-subband Tomonaga-Luttinger model
Takashi Kimura
We studied the conductance renormalization and conductivity of multi-subband Tomonaga-Luttinger models with inter-subband interactions. We found that, as in single-band systems, th…
d_{x^2-y^2}- vs. d_{xy}- like pairings in organic superconductors κ-(BEDT-TTF)_2 X
Kazuhiko Kuroki, Takashi Kimura, Ryotaro Arita +2
Pairing symmetry in -(BEDT-TTF)X is re-examined by applying fluctuation exchange method to the Hubbard model on the original four band lattice for the first time. Our study…
Flat-band ferromagnetism in quantum dot superlattices
Hiroyuki Tamura, Kenji Shiraishi, Takashi Kimura +1
Possibility of flat-band ferromagnetism in quantum dot arrays is theoretically discussed. By using a quantum dot as a building block, quantum dot superlattices are possible. We con…
Magnetic field effects on two-dimensional Kagome lattices
Takashi Kimura, Hiroyuki Tamura, Kenji Shiraishi +1
Magnetic field effects on single-particle energy bands (Hofstadter butterfly), Hall conductance, flat-band ferromagnetism, and magnetoresistance of two-dimensional Kagome lattices…
