Ultracold Chemical Reactions of a Single Rydberg Atom in a Dense Gas
Physical Review X, 2016 Within a dense environment (ρ≈10^{14} atoms/cm^{3}) at ultracold temperatures (T140 compared to 1 μs at n=90. In addition, a second observed reaction mechanism, namely, Rb_{2}^{+} molecule formation, was studied.

A photonic crystal receiver for Rydberg atom-based sensing [PDF]
Communications EngineeringRydberg atom-based sensors use atoms dressed by lasers to detect and measure radio frequency electromagnetic fields. The absorptive properties of the atomic gas, configured as a Rydberg atom-based sensor, change in the presence of a radio frequency ...

Scanning electron microscopy of Rydberg-excited Bose–Einstein condensates [PDF]
New Journal of Physics, 2014 We report on the realization of high resolution electron microscopy of Rydberg-excited ultracold atomic samples. The implementation of an ultraviolet laser system allows us to excite the atom, with a single-photon transition, to Rydberg states.

Long-Range Atom–Ion Rydberg Molecule: A Novel Molecular Binding Mechanism
Atoms, 2021 We present a novel binding mechanism where a neutral Rydberg atom and an atomic ion form a molecular bound state at a large internuclear distance. The binding mechanism is based on Stark shifts and level crossings that are induced in the Rydberg atom due

Long-range Rydberg-atom–ion molecules of Rb and Cs
Physical Review Research, 2021 We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a distant positive ion. The molecule is formed through long-range electric-multipole interaction between the Rydberg atom and the pointlike ion.

Quantum programming of the satisfiability problem with Rydberg atom graphs
Physical Review Research, 2023 Finding a quantum computing method to solve nondeterministic polynomial time (NP)-complete problems is currently of paramount importance in quantum information science. Here we propose and experimentally demonstrate a Rydberg atom approach to program the

Finding the Maximum Independent Sets of Platonic Graphs Using Rydberg Atoms
PRX Quantum, 2022 We present Rydberg-atom-array experiments performed to find the maximum independent sets of Platonic graphs. Three Platonic graphs—the tetrahedron, cube, and octahedron of Platonic solids—are constructed with atoms and Rydberg interatomic interactions ...

Composite spin approach to the blockade effect in Rydberg atom arrays
Physical Review Research, 2022 The Rydberg blockade induces strongly correlated many-body effects in Rydberg atom arrays, including rich ground-state phases and many-body scar states in the excitation spectrum.

Dynamics of atoms within atoms
New Journal of Physics, 2022 Recent experiments with Bose–Einstein condensates have entered a regime in which thousands of ground-state condensate atoms fill the Rydberg-electron orbit.

Anderson localization of a Rydberg electron
Physical Review Research, 2023 Highly excited Rydberg atoms inherit their level structure, symmetries, and scaling behavior from the hydrogen atom. We demonstrate that these fundamental properties enable a thermodynamic limit of a single Rydberg atom subjected to interactions with ...
