Line shapes and time dynamics of the Förster resonances between two Rydberg atoms in a time-varying electric field

“…[23] and an analytical model has been proposed. Another recent paper [24] reports on the broadening and overlapping of the Förster resonances in Rb Rydberg atoms at high density. Quasiforbidden Förster resonances in Cs Rydberg atoms were observed in Ref.…”

Control of Rydberg-atom blockade by dc electric-field orientation in a quasi-one-dimensional sample

“…Such calculation requires to consider all L states up to L = (n−1) for at least two manifolds above and below the state of interest. Since in this experiment n = 50, such calculation is more difficult and challenging than in our previous work [28], and it is under implementation [35].…”

“…Such difference is not surprising, and it may be due to two factors: i) The interaction between two Rydberg atoms is more complex than this simplistic potential based on the interaction parameter, obtained from the single-atom Stark effect, which is expected to be valid only at long range and not at the blocked regime. In a recent work, we have shown that the multilevel character of the interaction due to the presence of high angular momentum states is crucial for the calculation of accurate potential curves and interpretation of Rydberg interaction experiments [28]. Such calculation requires to consider all L states up to L = (n−1) for at least two manifolds above and below the state of interest.…”

“…Such magneto-optical trap is used to load a quasi-electrostatic trap (QUEST), producing a non-polarized atomic sample of ∼ 10 6 atoms at a peak density of ≈ 10 12 atoms/cm 3 and temperature of 60 µK. The QUEST is provided by a polarized 10.6 µm CO 2 laser (COHERENT model GEM-100), which is focused into the MOT volume with a waist of 15 µm and an available power of 80 W. More details on the experimental setup can be found in [27,28]. In order to excite the 50S 1/2 state, we apply a laser pulse train, which are subsequently detected by pulsedfield ionization (PFI).…”

Distinct antiblockade features of strongly interacting Rydberg atoms under a two-color weak excitation scheme

“…We now try to simulate the above experimental observations with a multilevel two-body theoretical model [38] by including different multipole-interaction-induced shifts of all magnetic sublevels of the Rydberg state based on the following two considerations. First, the lower (852 nm) and upper (510 nm) excitation lasers have Rabi frequencies p W =2 48. that couples levels | ñ g and | ñ r .…”
