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…
Buffer-gas cooling of a single ion in a multipole radio frequency trap beyond the critical mass ratio
B. Höltkemeier, P. Weckesser, H. López-Carrera +1
We theoretically investigate the dynamics of a trapped ion immersed in a spatially localized buffer gas. For a homogeneous buffer gas, the ion reaches a stable equilibrium only if…
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…
Direct observation of ultrafast many-body electron dynamics in an ultracold Rydberg gas
Nobuyuki Takei, Christian Sommer, Claudiu Genes +6
Many-body correlations govern a variety of important quantum phenomena such as the emergence of superconductivity and magnetism. Understanding quantum many-body systems is thus one…
Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances
J. Ulmanis, S. Häfner, R. Pires +3
We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 G and 1000 G. Cl…
