Selective ejection of atoms in a cold Rydberg gas

Abstract

We experimentally demonstrate that pairs of Rydberg atoms in a cold gas can be targeted by a precisely tuned microwave field that induces a strong dipole-dipole interaction that selectively ejects these atoms from the gas.

Dipole-Dipole Interactions in a Cold Rydberg Gas

Brian Richards

We investigate the strength and effects of dipole-dipole interactions in a cold Rydberg atom system. Our experiments explore the absence of collective decay due to dipole-dipole interactions, characterize dipole-dipole interactions and their dependence on Rydberg atom density and atomic motion, and explore possible methods to control atom separation using dipole-dipole interactions.

Microwave pump-probe spectroscopy of the dipole-dipole interaction in a cold Rydberg gas

Hyunwook Park, Thomas F. Gallagher, P. Pillet

Microwave pump-probe experiments starting with a cold gas of Rb $34s$ atoms confirm that cusped line shapes observed in dipole-dipole broadened microwave transitions are due to atoms which are widely separated and exhibit small dipole-dipole energy shifts. When the experiments are interpreted in terms of a nearest-neighbor model, they demonstrate that it is possible to select pairs of atoms based on their separation and orientation.

Electric Field Tuned Dipolar Interaction Between Rydberg Atoms

Yuechun Jiao, Jingxu Bai, Rong Song +3 more

We demonstrated a tuned dipole interaction between Rydberg atoms by employing a controllable electric field in a cold cesium ensemble. The | n P 3/2 ⟩ ( n = 38–40) Rydberg pairs are prepared with a three-photon scheme and detected via the state-selective field ionization technique. A weak DC electric field is used to tune the Rydberg pair interaction from the van der Waals interaction regime to the dipole–dipole interaction regime. The Förster resonant interaction and an adiabatic resonance energy transfer between the n P and n S Rydberg states are attained by precisely tuning the electric field. Rydberg excitation blockade with and without the electric field is investigated by changing the excitation pulse duration, which demonstrates that the dipole interaction–induced blockade effect is stronger than the van der Waals interaction–induced blockade effect. The precise control of the Rydberg interaction is of great significance to the coherent interaction in many-body systems and non-radiative collision processes.
