Abstract

The paper analyzes the Casimir/van Kampen dispersion interaction between two parallel graphene sheets using the Drude model for surface conductivity. It derives the force and pressure as functions of separation and chemical potential, and shows that the interaction is attractive, with a short-distance finite attraction and a long-distance inverse-fourth-power decay; at small chemical potential the force can exhibit a minimum and maximum as a function of distance.
