Relaxation of an isolated dipolar-interacting Rydberg quantum spin system
A. Piñeiro Orioli, A. Signoles, H. Wildhagen +4
How do isolated quantum systems approach an equilibrium state? We experimentally and theoretically address this question for a prototypical spin system formed by ultracold atoms pr…
Correlated Exciton Transport in Rydberg-Dressed-Atom Spin Chains
H. Schempp, G. Günter, S. Wüster +2
We investigate the transport of excitations through a chain of atoms with non-local dissipation introduced through coupling to additional short-lived states. The system is describe…
Full counting statistics of laser excited Rydberg aggregates in a one-dimensional geometry
H. Schempp, G. Günter, M. Robert-de-Saint-Vincent +8
We experimentally study the full counting statistics of few-body Rydberg aggregates excited from a quasi-one-dimensional Rydberg gas. We measure asymmetric excitation spectra and i…
An experimental approach for investigating many-body phenomena in Rydberg-interacting quantum systems
C. S. Hofmann, G. Günter, H. Schempp +6
Recent developments in the study of ultracold Rydberg gases demand an advanced level of experimental sophistication, in which high atomic and optical densities must be combined wit…
Sub-Poissonian statistics of Rydberg-interacting dark-state polaritons
Christoph S. Hofmann, Georg Günter, Hanna Schempp +5
Interfacing light and matter at the quantum level is at the heart of modern atomic and optical physics and enables new quantum technologies involving the manipulation of single pho…
Spontaneous avalanche ionization of a strongly blockaded Rydberg gas
M. Robert-de-Saint-Vincent, C. S. Hofmann, H. Schempp +3
We report the sudden and spontaneous evolution of an initially correlated gas of repulsively interacting Rydberg atoms to an ultracold plasma. Under continuous laser coupling we cr…
Interaction enhanced imaging of individual atoms embedded in dense atomic gases
G. Günter, M. Robert-de-Saint-Vincent, H. Schempp +3
We propose a new all-optical method to image individual atoms within dense atomic gases. The scheme exploits interaction induced shifts on highly polarizable excited states, which…
Coherent Population Trapping with Controlled Interparticle Interactions
H. Schempp, G. Günter, C. S. Hofmann +7
We investigate Coherent Population Trapping in a strongly interacting ultracold Rydberg gas. Despite the strong van der Waals interactions and interparticle correlations, we observ…
