Polarization Plateau in Atomic Fermi Gas Loaded on Triangular Optical Lattice
M. Okumura, S. Yamada, M. Machida +1
In order to demonstrate that atomic Fermi gas is a good experimental reality in studying unsolved problems in frustrated interacting-spin systems, we numerically examine the Mott c…
Magnetism Localization in Spin-Polarized One-Dimensional Anderson-Hubbard Model
M. Okumura, S. Yamada, N. Taniguchi +1
In order to study an interplay of disorder, correlation, and spin imbalance on antiferromagnetism, we systematically explore the ground state of one-dimensional spin-imbalanced And…
Hole Localization in One-Dimensional Doped Anderson-Hubbard Model
M. Okumura, S. Yamada, N. Taniguchi +1
We study the interplay of disorder and correlation in the one-dimensional hole-doped Hubbard-model with disorder (Anderson-Hubbard model) by using the density-matrix renormalizatio…
Stripe Formation in Fermionic Atoms on 2-D Optical Lattice inside a Box Trap: DMRG Studies for Repulsive Hubbard Model with Open Boundary Condition
M. Machida, M. Okumura, S. Yamada
We suggest that box shape trap enables to observe intrinsic properties of the repulsive Hubbard model in a fixed doping in contrast to the harmonic trap bringing about spatial vari…
Comment on "Novel Superfluidity in a Trapped Gas of Fermi Atoms with Repulsive Interaction Loaded on an Optical Lattice"
M. Rigol, S. R. Manmana, A. Muramatsu +3
In a recent letter Machida et al. [Phys. Rev. Lett. 93, 200402 (2004)] concluded that in a trapped gas of fermions with repulsive interactions a superfluid phase appears around the…
