Ultracold long-range van der Waals Rydberg trimers

Communications Physics
Rydberg molecules are an essential ingredient of cold molecular sciences. Due to the richness of interactions between Rydberg atoms and neutral atoms, new kinds of Rydberg molecules and binding mechanisms are still to be discovered.

Rydberg Atom-Based Sensors: Principles, Recent Advances, and Applications

Photonics
Rydberg atoms are neutral atoms excited to high principal quantum number states, which endows them with exaggerated properties such as large electric dipole moments, long lifetimes, and extreme sensitivity to external electromagnetic fields.

Expanding the neutral-atom gate set: Native iSWAP and exchange gates from dipolar Rydberg interactions

Physical Review Research
We present a native realization of iSWAP and parametrized exchange gates for neutral-atom quantum processing units. Our approach leverages strong dipole-dipole interactions between two different dipole-coupled Rydberg states, employing optimal control ...

Rydberg atom in gravity

Journal of Physics: Conference Series, 2014
The local position invariance of a physical system is examined using a Rydberg atom and the universality of free fall is found to be invalid for a quantum system. A Rydberg atom is analysed in Newtonian gravity and curved space. The energy is found to vary as n2 for very large values of the principal quantum number n. The change in energy is calculated

Cooperative interactions in dense thermal Rb vapour confined in nm-scale cells [PDF]

, 2013
This thesis presents an investigation of the fundamental interaction between light and matter, realised with a rubidium vapour confined in a cell whose thickness (in the propagation direction) is less than the optical wavelength.

Studies in Ultracold Ground State Atom-Rydberg Atom Interactions

, 2017
Collisions involving Rydberg atoms reveal detailed information on the state of a background medium and can be used as diagnostic probes of temperature and density distributions in a neutral or ionized gas.

Cavity-enhanced Rydberg atom microwave receiver [PDF]

Developing microwave electric field sensing based on Rydberg atom has received significant attention due to its unique advantages. However, achieving effective coupling between Rydberg atom and the microwave electric field in the sensing process is a ...

Hilbert space fragmentation in a driven-dephasing Rydberg atom array

Physical Review Research
We investigate the onset and mechanism of Hilbert space fragmentation (HSF) in a chain of strongly interacting Rydberg atoms subjected to local dephasing.
