摘要: We investigate effects of pseudo-spin population imbalance on Mott phases in 1D trapped two-component atomic Fermi gases loaded optical lattices based the repulsive Hubbard model harmonic traps. By using density matrix renormalization group method, we numerically calculate profiles each component and clarify magnetism. Consequently, find that all features from weakly to fully polarized cases are well described by S=1/2 antiferromagnetic Heisenberg chain under magnetic field. These results indicate offer experimental stages for studying various interacting spin systems.
