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 pairs, ...

Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external ...

Scientists have developed a novel technique to let atoms interact over large distances. Scientists at the MPQ (Garching) and MPIPKS (Dresden) have developed a novel technique to let atoms interact ...

Rydberg atoms, characterised by electrons in high principal quantum number orbits, exhibit exaggerated properties such as large dipole moments and long lifetimes. These features render them uniquely ...

Additional laser beams excite a second atom into the Rydberg state. The electric field of the ion deforms this gigantic atom. Interestingly the deformation can be attractive or repulsive depending on ...
