Abstract
A quantum Monte Carlo study at zero temperature of twodimensional H2 on top of a solid Rb surface is presented. The lattice constituted by the alkali atoms frustrates the formation of solid H2, which is the natural phase of pure two-dimensional H2. Therefore, H2 with the Rb atoms acting like fixed impurities remains in a liquid phase even at zero temperature. We present resugts for the H2 equation of state, structural properties, superfluid density and condensate fraction for a fixed Rb lattice.
