摘要: We study the three-fermion problem within a 1D model of Feshbach resonance in order to gain insight into how Fulde-Ferrell-Larkin-Ovchinnikov (FFLO)-like state at small negative scattering lengths evolves Bose-Fermi mixture positive lengths. The FFLO possesses an oscillating superfluid correlation function, while correlations are monotonic. find that this behavior is already present three-body level. exact and extra insights by considering world lines path-integral Monte Carlo calculation.
