Digital quantum simulation with Rydberg atoms [PDF]
Quantum Information Processing, 2011 We discuss in detail the implementation of an open-system quantum simulator with Rydberg states of neutral atoms held in an optical lattice. Our scheme allows one to realize both coherent as well as dissipative dynamics of complex spin models involving many-body interactions and constraints.

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.

Comparing Homodimer and Homotrimer Noncovalent Complexes Involving Coinage Metals: A Theoretical Perspective. [PDF]
ChemphyschemIn this study, the ability of M2 clusters (M = Cu, Ag, and Au) to form noncovalent homodimers/homotrimers has been evaluated at the RI‐PBE0‐D4/def2‐TZVPD level of theory. The results have been complemented with QTAIM, NCIplot, and EDA analyses, which helped to shed light on the physical nature of these unconventional noncovalent contacts. In this study,

A coherent quantum annealer with Rydberg atoms [PDF]
Nature Communications, 2017 AbstractThere is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner ...

New 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
Physical 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 ...

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

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