    "abstract": "We consider the van der Waals interaction between two ground-state atoms\nembedded in adjacent semi-infinite magnetodielectric media, with emphasis on\nmedium effects on it. We demonstrate that, in this case, at small atom-atom\ndistances the van der Waals interaction is screened by the surrounding media in\nthe same way as in an effective (single) medium. At larger atomic distances,\nhowever, its dependence on the material parameters of the system and the\npositions of the atoms is more complex. We also calculate the Casimir-Polder\npotential of an atom A arising from a uniform distribution of atoms B in the\nmedium across the interface. Comparison of this potential with the\ncorresponding result deduced from the Casimir force on a thin composite slab in\nfront of a composite semi-infinite medium, both obeying the Clausius-Mossotti\nrelation, suggests a hint on how to improve a well-known formula for the van\nder Waals potential with respect to the local-field effects.",
