Interaction of two Rydberg atoms in the vicinity of an optical nanofibre

We consider two rubidium atoms, prepared in the same S or P Rydberg states near an optical nanofibre. determine van der Waals interaction between them and identify novel features, including reshaping of anisotropy formation potential well nanofibre for states. attribute these phenomena to breaking rotation symmetry around interatomic axis due presence fibre. Our work constitutes important step assessment atom-nanofibre quantum interfaces devices.
