Chiral Prethermalization in supersonically split condensates
Kartiek Agarwal, Emanuele G. Dalla Torre, Bernhard Rauer +3
We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a supersonic unzipping of a single condensate. We use the Lorentz invariance of t…
Local emergence of thermal correlations in an isolated quantum many-body system
Tim Langen, Remi Geiger, Maximilian Kuhnert +2
We experimentally demonstrate how thermal properties in an non-equilibrium quantum many- body system emerge locally, spread in space and time, and finally lead to the globally rela…
Quantum state manipulation and cooling of ultracold molecules
Tim Langen, Giacomo Valtolina, Dajun Wang +1
An increasingly large variety of molecular species are being cooled down to low energies in recent years, and innovative ideas and powerful techniques continue to emerge to gain ev…
High Resolution Imaging of Single Atoms in a Quantum Gas
Tatjana Gericke, Peter Würtz, Daniel Reitz +2
Our knowledge on ultracold quantum gases is strongly influenced by our ability to probe these objects. In situ imaging combined with single atom sensitivity is an especially appeal…
High-resolution spectroscopy of barium monofluoride: Odd isotopologues, hyperfine structure and isotope shifts
Felix Kogel, Yuly Chamorro, Mangesh Bhattarai +5
Barium monofluoride (BaF) is a promising molecular species for precision tests of fundamental symmetries and interactions. We present a combined theoretical and experimental study…
Roton Excitations in an Oblate Dipolar Quantum Gas
Jan-Niklas Schmidt, Jens Hertkorn, Mingyang Guo +7
We observe signatures of radial and angular roton excitations around a droplet crystallization transition in dipolar Bose-Einstein condensates. In situ measurements are used to cha…
