Rydberg atoms with principal quantum number n⪢ 1 have exaggerated atomic properties
including dipole-dipole interactions that scale as n 4 and radiative lifetimes that scale as n 3 …

We review here the studies performed about interactions in an assembly of cold Rydberg
atoms. We focus especially on the review of the dipole–dipole interactions and on the effect …

The ac Stark effect was used to induce resonant energy transfer between translationally cold
Rb 85 Rydberg atoms. When a 28.5 GHz dressing field was set at specific field strengths, the …

Long-range interactions between cold Rydberg atoms, which are used in many important
applications, can be enhanced using Förster resonances between collective many-body …

This thesis describes the first demonstration of a cooperative optical non-linearity based on
Rydberg excitation. Whereas in conventional non-linear optics the non-linearity arises …

A nonresonant microwave dressing field at 38.465 GHz was used to eliminate the static
electric dipole moment difference between the 49 s 1/2 and 48 s 1/2 Rydberg states of 87 Rb …

We investigate the interaction between Rydberg atoms, whose electronic states are dressed
by multiple microwave fields. Numerical calculations are used for an exact description of the …

In this chapter, we present a review of Rydberg atom interactions. The review focusses on
the importance of these interactions in ultracold Rydberg atom physics. We address how …

Abstract Rydberg Atome sind auf Grund ihrer starken und kontrollierbaren
Wechselwirkungen gut geeignet zur Quantensimulation von lang-reichweitig …

Atom-atom interactions within a small volume were investigated through the excitation of
ultracold Rb atoms. The application of microwaves enhances these interactions, causing the …
