    "abstract": "A recently developed Quantum Monte Carlo algorithm based on the stochastic\nevolution of Hartree-Fock states has been applied to compute the static\ncorrelation functions of a one-dimensional model of attractively interacting\ntwo component fermions. The numerical results have been extensively compared to\nexisting approximate approaches. The crossover to a condensate of pairs can be\nidentified as the first-order pair coherence extending throughout the whole\nsize of the system. The possibility of revealing the onset of the transition\nwith other observables such as the density-density correlations or the\nsecond-order momentum space correlations is discussed.",
