Abstract
Using quantum Monte Carlo we have studied the superfluid density of the first layer of He4 and H2 adsorbed on graphene and graphite. Our main focus has been on the equilibrium ground state of the system, which corresponds to a registered 3¿×3¿ phase. The perfect solid phase of H2 shows no superfluid signal, whereas He4 has a finite but small superfluid fraction (0.67%). The introduction of vacancies in the crystal makes the superfluidity increase, showing values as large as 14% in He4 without destroying the spatial solid order.
