Abstract
We report results of fully non-perturbative calculations, based on Auxiliary Field Quantum Monte Carlo (AFQMC) approach, for the dilute neutron matter at the density ρ = 0.003 fm -3. Fundamental quantities which characterize the superfluid state: the single particle energy gap Δ(T), and the critical temperature Tc have been determined. The large value of Δ(0)/Tc ≈ 3.2 indicates that the system is not a BCS-type superfluid at low temperatures.
