"Normal fluid phases of 3He in two dimensions"

I will present ongoing work, based on quantum Monte Carlo simulations, on the normal fluid phase of 3He in two dimensions, both for the strictly 2D case and for more realistic models of monolayers adsorbed on different substrates. We find close agreement with the experiment for both the static spin susceptibility and the dynamic structure factor. For weak enough alkali metal substrates, we predict a gas-liquid phase transition not found for strictly 2D 3He.
