摘要：

A quantum Monte Carlo study at zero temperature of two-dimensional H-2 on top of a solid Rb surface is presented. The lattice constituted by the alkali atoms frustrates the formation of solid H-2, which is the natural phase of pure two-dimensional H-2. Therefore, H-2 with the Rb atoms acting like fixed impurities remains in a liquid phase even at zero temperature. We present results for the H-2 equation of state, structural properties, superfluid density and condensate fraction for a fixed Rb lattice.
