Two photons (depicted above left as waves), can be locked together at a short distance. Under exposure to Rydberg atoms, the photons can form a state resembling a two-atom molecule. (Courtesy: E ...

Subsequently, an ultrashort pulse laser light lasting just 10 picoseconds was used to produce the quantum superposition of the ground state with an electron in the 5s orbital and the Rydberg state ...

The resulting order of the atoms is a well-controlled starting state for the next, decisive step: the implementation of "Rydberg-dressing" by shining in very intense, ultraviolet laser light.

Atoms in the optical lattice, trapped at a distance of 0.5 micron, are excited to the Rydberg state by the ultrafast excitation technique. Interaction between close Rydberg atoms results in the ...

The Rydberg atom's electron is scattered very slightly by the neutral atoms in its path, but because the electron is so slow it isn't transferred into another state.

A research team has observed multibody interaction-induced EPs and hysteresis trajectories in cold Rydberg atomic gases. They revealed the phenomenon of charge-conjugation parity (CP) symmetry ...

The scientists take this hurdle by choosing a very unequal superposition, in which the atoms are in the unstable Rydberg state only with a small probability. "To some extent, ...

The Rydberg state is widespread in a variety of physical platforms such as atoms, molecules, and solids. In particular, Rydberg excitons are highly excited Coulomb-bound states of electron–hole ...
