Theoretical Results

We present theoretical results for the radial distribution function g(r) and the static liquid structure function S(k) of liquid para-hydrogen at low temperatures. The results have been obtained via quantum Monte Carlo Path Integral simulations, classical Monte Carlo calculations, and correlated density matrix theory.

Superfluid State

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.
