Abstract:We investigate the thermal Casimir-Polder (CP) potential of 87 Rb atoms in Rydberg nS-states near single-and double-layer graphene. The dependence of the CP potential on parameters such as atom-surface distance, temperature, principal quantum number n and graphene Fermi energy are explored. Through large scale numerical simulations, we show that, in the non-retarded regime, the CP potential is dominated by the non-resonant and evanescent-wave terms which are monotonic, and that, in the retarded regime, the CP … Show more
