We study spin imbalance effects on the Josephson junction of superconductors under a strong magnetic field and the grey soliton in spin-polarized ultracold Fermi gas. We obtain the exact solution for the condensates with arbitrary spin imbalance and the fermion spectrum perturbatively in the presence of small spin imbalance.
