We investigate the effect of van der Waals forces on a collection of granular particles by means of molecular
dynamics simulations of a vibrated system in three dimensions. The van der Waals interactions introduce two
phase coexistences: one between a random close packing and a gas and a second between a polycrystalline
dense state and a gas, where the dense, disordered component crystallizes when the driving amplitude exceeds a
threshold value. The region of stability of the ordered state in the nonequilibrium phase diagram grows in size
as the Hamaker constant increases or the degree of dissipation increases.
