An ultracold heavy Rydberg system formed from ultra-long-range molecules bound in a stairwell potential

open access: yesNew Journal of Physics, 2020
We propose a scheme to realize a heavy Rydberg system (HRS), a bound pair of oppositely charged ions, from a gas of ultracold atoms. The intermediate step to achieve large internuclear separations is the creation of a unique class of ultra-long-range ...

Giant-atom effects on population and entanglement dynamics of Rydberg atoms in the optical regime

open access: yesPhysical Review Research, 2023
Giant atoms are attracting interest as an emerging paradigm in the quantum optics of engineered waveguides. At variance with the well-known artificial giant atoms for microwave photonics, here we propose the archetype of a giant atom working in the ...

Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and

Experiments in Cavity QED: Exploring the Interaction of Quantized Light with a Single Trapped Atom [PDF]

open access: yes, 2005
The experiments discussed in this thesis focus on the interaction of a single trapped atom with the single mode of a high-finesse optical cavity, in the regime of strong coupling.

Electromagnetically Induced Transparency with Rydberg Atoms [PDF]

open access: yesPhysical Review Letters, 2011
We present a theory of electromagnetically induced transparency in a cold ensemble of strongly interacting Rydberg atoms. Long-range interactions between the atoms constrain the medium to behave as a collection of superatoms, each comprising a blockade volume that can accommodate at most one Rydberg excitation.

Dynamical generation of chiral W and Greenberger-Horne-Zeilinger states in laser-controlled Rydberg-atom trimers

open access: yesPhysical Review Research, 2022
Motivated by the significantly improved scalability of optically trapped neutral-atom systems, extensive efforts have been devoted in recent years to quantum-state engineering in Rydberg-atom ensembles.

Generation of cold Rydberg atoms at submicron distances from an optical nanofiber

open access: yesPhysical Review Research, 2020
We report on a controllable, hybrid quantum system consisting of cold Rydberg atoms and an optical nanofiber interface. Using a two-photon ladder-type excitation in ^{87}Rb, we demonstrate both coherent and incoherent Rydberg excitation at submicron ...

Diffraction of Rydberg Atoms by Laser Light [PDF]

open access: yesPhysical Review Letters, 1992
It is shown that semiclassical path representations provide a well-suited framework for the description of the diffraction of Rydberg atoms by laser light. They allow one to relate the momentum exchange between the atomic center-of-mass motion and the laser field directly to elementary laser-assisted collisions between the excited Rydberg electron and ...

Observation of spin-orbit-dependent electron scattering using long-range Rydberg molecules

open access: yesPhysical Review Research, 2020
We present experimental evidence for spin-orbit interaction of an electron as it scatters from a neutral atom. The scattering process takes place within a Rb_{2} ultralong-range Rydberg molecule, consisting of a Rydberg atomic core, a Rydberg electron ...
