Sympathetic cooling of OH- ions using ultracold Rb atoms in a dark SPOT
H. López, B. Höltkemeier, J. Glässel +5
We are developing a new hybrid atom-ion trap to study the interaction of ultracold rubidium atoms with mass-selected OH- molecules. The ions are trapped inside an octupole rf-trap…
Internal state thermometry of cold trapped molecular anions
R. Otto, A. von Zastrow, T. Best +1
Photodetachment spectroscopy of OH- and H3O2- anions has been performed in a cryogenic 22-pole radiofrequency multipole trap. Measurements of the detachment cross section as a func…
Photodetachment as destruction mechanism for CN- and C3N- anions in circumstellar envelopes
S. S. Kumar, D. Hauser, R. Jindra +5
Absolute photodetachment cross sections of two anions of astrophysical importance CN- and C3N- were measured to be (1.18 +- (0.03)_stat (0.17)_sys) * 10^-17 cm^2 and (1.43 +- (0.14…
Reactive collisions of trapped anions with ultracold atoms
Johannes Deiglmayr, Anna Göritz, Thorsten Best +2
We present a scheme to embed molecular anions in a gas of ultracold rubidium atoms as a route towards the preparation of cold molecular ions by collisional cooling with ultracold a…
Coherent Interaction of a Single Fermion with a Small Bosonic Field
Sebastian Will, Thorsten Best, Simon Braun +2
We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival s…
Fermionic transport in a homogeneous Hubbard model: Out-of-equilibrium dynamics with ultracold atoms
Ulrich Schneider, Lucia Hackermüller, Jens Philipp Ronzheimer +8
Transport properties are among the defining characteristics of many important phases in condensed matter physics. In the presence of strong correlations they are difficult to predi…
