Adsorbate dynamics on a silica-coated gold surface measured by Rydberg Stark spectroscopy

Trapping a Rydberg atom close to a surface is an important step towards the realisation of many proposals for quantum information processing or hybrid quantum systems. One of the challenges in these experiments is posed by the electric field emanating from contaminations on the surface. Here we report on measurements of an electric field created by 87 Rb atoms adsorbed on a 25 nm thick layer of SiO 2 , covering a 90 nm layer of Au. The electric field is measured using a two-photon transition to the and states. The electric field value that we measure is higher than typical values measured above metal surfaces, but is consistent with a recent measurement above a SiO 2 surface. In addition, we measure the temporal behaviour of the field and observe that we can reduce it in a single experimental cycle, using ultraviolet light or by mildly locally heating the surface with one of the excitation lasers, whereas the buildup of the field takes thousands of cycles. We explain these results by a change in the adatom distribution on the surface. These results indicate that, while the stray electric field can be reduced, achieving field-free conditions above a silica-coated gold chip remains challenging.

Experimental study of Au atom Rydberg states

G. Ding, R. C. Shang, Lan Fen Chang +3 more

A beam of gold atoms was produced by heating the gold-containing material by an electro-thermal method. Two UV laser beams then irradiated the atomic beam perpendicularly, which excited the Au atoms to very high Rydberg states from their ground states (6S1/2). A high voltage pulsed electric field was then applied to the interaction region approximately 200 ns after the laser pulse, ionising the Au atoms in Rydberg states. By scanning the wavelength of the laser over a certain range, the positions of 38 energy levels of Au atoms in the n 2D3/2 (n=18-38) and n 2S1/2 (n=21-34, 36-38) series have been measured. The ionisation limits of the n 2D3/2 and n 2S1/2 series were determined by parametric fitting to be Ed=74 409.8 (3) cm-1 and Es=74 410.0 (2) cm-1, respectively. The quantum defects of all these levels were also calculated. This measurement is the first for Au in the energy range and channels mentioned above.
