Revealing short-range non-Newtonian gravity through Casimir-Polder shielding

摘要: We carry out a realistic, yet simple, calculation of the Casimir-Polder interaction in presence metallic shield order to aid design experiments test non-Newtonian gravity. In particular, we consider rubidium atom near movable silicon slab with gold film between. show that by moving various distances and making precise measurements force exerted on atom, one could principle discern existence short-range modifications Newtonian This avoids need for patterned surface where calculations are much harder which probe must be moved laterally at fixed distance. also briefly discuss case an atomic cloud undergoes Bloch oscillations within optical lattice created reflecting laser off shield. find our scheme has potential improve current constraints if relatively modest improvements localisation lattices made.
