“…Thus measurements of ionization fractions and their asymmetry can be mapped to the polarization of the initial state. In the second approach, the quasi-1D atoms are used as a starting point to engineer localized wave packets that travel in near-circular Bohr-like orbits [21,22]. To create such states quasi-1D atoms polarized along (say) the x axis are subject to a transverse pump field, F pump , that is suddenly applied (T rise T n ) along the z axis.…”

The efficient production of very-high-n, n ∼ 300, quasi-one-dimensional (quasi-1D) strontium Rydberg atoms through three-photon excitation of extreme Stark states in the presence of a weak dc field is demonstrated using a crossed laser-atom beam geometry. Strongly polarized quasi-1D states with large permanent dipole moments ∼1.2n 2 a.u. can be created in the beam at densities (∼10 6 cm −3) where dipole blockade effects should become important. A further advantage of three-photon excitation is that the product F states are sensitive to the presence of external fields, allowing stray fields to be reduced to very small values. The experimental data are analyzed using quantum calculations based on a two-active-electron model together with classical trajectory Monte Carlo simulations. These allow determination of the atomic dipole moments and confirm that stray fields can be reduced to 25 μV cm −1 .

“…[1] of nonspreading wave packets describing Rydberg electrons driven by a circularly polarized wave was recently fully confirmed in experiments [2,3]. The dynamics of these nonstationary but stable electronic states resembles the dynamics of Trojan asteroids in the Sun-Jupiter system.…”

We propose a simple three-body model of an atom in which one electron on a circular Rydberg orbit is treated as an independent particle and the remaining core electrons are collectively described as a single object. Within this model we predict the existence of stable deformed states of atoms. The deformation is generated by a bootstrap mechanism. The atomic core is polarized by the excited electron and the induced dipole moment keeps this electron localized. The deformed stable states of the atom are similar to the Trojan states observed in recent experiments. However, in the present case the breaking of the rotational symmetry does not require the presence of external fields.Comment: 0 pages, 10 figures, to be published in Phys. Rev.

“…Dephasing of Rydberg wave packets is a subject that has found renewed interest in particular in relation to noiseinduced decoherence in cold open quantum systems [24,25]. In the work by Wyker et al [26], Rydberg atoms in nearly circular high angular momentum states (l ∼ n) and high principal quantum number n ∼ 300 were studied subject to stochastic electric noise and collisions.…”
