Density-Matrix Renormalization Group Study of Trapped Imbalanced Fermi Condensates

摘要: The density-matrix renormalization group is employed to investigate a harmonically trapped imbalanced Fermi condensate based on one-dimensional attractive Hubbard model. obtained density profile shows flattened population difference of spin-up and spin-down components at the center trap, exhibits phase separation between unpaired majority atoms for certain range interaction imbalance P. two-particle matrix reveals that sign order parameter changes periodically, demonstrating realization Fulde-Ferrell-Larkin-Ovchinnikov phase. minority spin contribute quasicondensate up least P{approx_equal}0.8. Possible experimental situations test our predictions are discussed.
