We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy
transport through collective eigenstates, considering isolated atoms or assemblies …

We show that an array of ultracold Rydberg atoms embedded in a laser driven background
gas can serve as an aggregate for simulating exciton dynamics and energy transport with a …

Long-range interparticle interactions are revealed in extremely dilute thermal atomic
ensembles using highly sensitive nonlinear femtosecond spectroscopy. Delocalized …

We show how to create long-range interactions between alkali atoms in different hyperfine
ground states, with the goal of coherent quantum transport. The scheme uses off-resonant …

We show how the phase profile of Bose-Einstein condensates can be engineered through
its interaction with localized Rydberg excitations. The interaction is made controllable and …

Adiabaticity is crucial for our understanding of complex quantum dynamics and thus for
advancing fundamental physics and technology, but its impact cannot yet be quantified in …

Phase-modulated nonlinear spectroscopy with higher harmonic demodulation has recently
been suggested to provide information on many-body excitations. In the present work we …

In Rydberg dressed ultracold gases, ground-state atoms inherit properties of a weakly
admixed Rydberg state, such as sensitivity to long-range interactions. We show that through …

The long-range dipole-dipole interaction can create delocalized states due to the exchange
of excitation between Rydberg atoms. We show that even in a random gas many of the …
