Metastable decoherence-free subspaces and electromagnetically induced transparency in interacting many-body systems
Katarzyna Macieszczak, YanLi Zhou, Sebastian Hofferberth +3
We investigate the dynamics of a generic interacting many-body system under conditions of electromagnetically induced transparency (EIT). This problem is of current relevance due t…
Rydberg dressing: Understanding of collective many-body effects and implications for experiments
Jonathan B. Balewski, Alexander T. Krupp, Anita Gaj +3
The strong interaction between Rydberg atoms can be used to control the strength and character of the interatomic interaction in ultracold gases by weakly dressing the atoms with a…
Amplifying single impurities immersed in a gas of ultra cold atoms
B. Olmos, W. Li, S. Hofferberth +1
We present a method for amplifying a single or scattered impurities immersed in a background gas of ultra cold atoms so that they can be optically imaged and spatially resolved. Ou…
Weakly interacting Bose gas in the one-dimensional limit
P. Krüger, S. Hofferberth, I. E. Mazets +2
We prepare a chemically and thermally one-dimensional (1d) quantum degenerate Bose gas in a single microtrap. We introduce a new interferometric method to distinguish the quasicond…
Two-point density correlations of quasicondensates in free expansion
S. Manz, R. Bücker, T. Betz +8
We measure the two-point density correlation function of freely expanding quasicondensates in the weakly interacting quasi-one-dimensional (1D) regime. While initially suppressed i…
Density ripples in expanding low-dimensional gases as a probe of correlations
A. Imambekov, I. E. Mazets, D. S. Petrov +6
We investigate theoretically the evolution of the two-point density correlation function of a low-dimensional ultracold Bose gas after release from a tight transverse confinement.…
