“…However, the first experiment to observe evidence of its anisotropy, was carried out in 2004 by Carrol et al [17]. In this work, the authors have observed the electric field angular dependence of the dipole-dipole interaction in a quasi-unidimensional sample created by a confined laser beam geometry.…”

“…An additional parameter accessible for non-zero angular momentum states is the dependence on the alignment of the dipoles [27]. This could be explored with the application of a weak electric field, potentially enabling an external switch to turn the blockade-mechanism on or off.…”

Abstract. We use the technique of electro-magnetically induced transparency (EIT) to probe the effect of attractive dipole-dipole interactions in a highly excited Rydberg gas. The transient character of the EIT response is investigated by rapidly scanning the probe laser through resonance. We characterize the resulting cooperative optical non-linearity as a function of probe strength, density and scan direction. For the 58D 5/2 Rydberg state, an atom density of 1.6 × 10 10 cm −3 and a positive frequency scan we measure a third-order non-linearity of χ (3) = 5 × 10 −7 m 2 V −2 . For the reverse scan we observe a second order non-linearity of χ (2) = 5 × 10 −6 mV −1 . The contrasting behaviour can be explained in terms of motional effects and resonant excitation of Rydberg pairs.

“…Instead, work has concentrated on the dynamical aspects of resonant energy transfer between cold Rydberg atoms. For example, Carroll et al [6] have recently studied how the relative orientation of the electric field with respect to the spatial orientation of two Rydberg atoms influences their dipoledipole interaction. They used cold Rb atoms obtained from a magneto-optical trap (MOT) to study the process: 32d + 32d → 34p + 30k, where 30k represents the Starkstates centered around n = 30.…”

Determination of theRb85ng-series quantum defect by electric-field-induced resonant energy transfer between cold Rydberg atoms

et al. 2006

Resonant energy transfer between cold Rydberg atoms was used to determine Rydberg atom energy levels, at precisions approaching those obtainable in microwave spectroscopy. Laser cooled 85 Rb atoms from a magneto-optical trap were optically excited to 32d 5/2 Rydberg states. The two-atom process 32d 5/2 + 32d 5/2 → 34p 3/2 + 30g is resonant at an electric field of approximately 0.3 V/cm. This process is driven by the electric dipole-dipole interaction, which is allowed due to the partial f character that the g state acquires in an electric field. The experimentally observed resonant field, together with the Stark map calculation is used to make a determination of the 85 Rb ng-series quantum defect: δg(n = 30) = 0.00405(6).
