Quantum computing with Rydberg atom graphs
Journal of the Korean Physical Society, 2023 In recent years, Rydberg atom graphs, which are the arrangement of atoms of which the interaction through Rydberg state excitation can be represented by a mathematical graph, have emerged as a promising qubit platform for quantum computing and quantum ...

Physical Review A, 1986
Ion formation in sodium vapor (\ensuremath{\sim}${10}^{11}$ ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}3}$) containing Rydberg atoms (18\ensuremath{\le}n\ensuremath{\le}35) was investigated. Both atomic ions and diatomic molecular ions resulting from collisions between highly excited sodium, ${\mathrm{Na}}^{\mathrm{*}\mathrm{*}}$, and Na(3s) were observed.

Resonant Rydberg-Atom-Rydberg-Atom Collisions
Physical Review Letters, 1981We have observed the sharply resonant enhancement of the cross section of the collision process $ns+ns\ensuremath{\rightarrow}np+(n\ensuremath{-}1)p$ between two $\mathrm{Na}ns$ ($16l~nl~27$) atoms which occurs when the levels are shifted by an electric field so that the $ns$ level lies midway between the two $p$ states.

Subrecoil cooling of Rydberg atoms
Physical Review A, 1995Two mechanisms for production of an ensemble of atoms in a highly excited state with very narrow distribution of the atomic center-of-mass momentum (cold Rydberg atoms) are proposed. The mechanisms are based on velocity-selective $\ensuremath{\pi}$ pulses and coherent population trapping in three-level cascade systems with the uppermost state being the

Squeezing in a Rydberg Atom Maser
Physical Review Letters, 1985We show theoretically that a Rydberg atom maser produces during its evolution a squeezed field with sub-Poissonian statistics. We give a semiclassical interpretation of this effect.

Radiative Rydberg-atom–Rydberg-atom collisions in the strong-field regime
Physical Review A, 1987We describe the experimental observation of the resonant collisional energy transfer Na(ns)+Na(ns)+qh\ensuremath{\nu}\ensuremath{\rightarrow}Na(np)+Na[(n-1)p]+(q○)h\ensuremath{\nu} which occurs when the Na atoms in a strong microwave field are tuned in energy with a static field so that the energy resonance ${E}_{\mathrm{ns}}$+${E}_{\mathrm{ns}}$=${E}_{

Strong autoresonance excitation of Rydberg atoms: The Rydberg accelerator
Physical Review A, 1990A classical mechanism is proposed for the many-photon ionization of Rydberg atoms in a quasimonochromatic oscillating electric field with an amplitude smaller than the stochasticity threshold. The mechanism is based on the dynamic autoresonance between the slowly varying frequency of the oscillating field and the Keplerian frequency (or one of its ...

Rydberg-atom-Rydberg-atom ionisation cross sections
Journal of Physics B: Atomic and Molecular Physics, 1979A four-body classical-trajectory Monte Carlo method has been applied to Rydberg-atom-Rydberg-atom scattering problems. Numerical calculations were conducted over the velocity range ve/3 to 3v2 where v2(au)=1/n and n is the principal quantum number of the Rydberg atom.

Journal of Modern Optics, 1987
Abstract It is shown that some 17 Rydberg Na atoms initially placed into a coherent atomic state and super-radiating into a low-Q microwave cavity at temperatures T ≲ 0·4 K will show modest squeezing in the fluorescence field, the squeezing arising from terms oscillating at twice the cavity frequency.
