摘      要：We find for the first time that a model Hamiltonian or s-wave superconductors in tne presence or spm-orbit interactions and a Zeeman field is exactly solvable. Most intriguingly, based on the exact solutions, a novel type of Fulde Ferrel-Larkin-Ovchinnikov ground state is rigorously revealed, in which the center-of-mass momentum of the fermion pair is proportional to the Zeeman field. We also generalize our exact analysis to the spin-orbit- coupled Bose-Einstein condensate.
