Experimental characterization of singlet scattering channels in long-range Rydberg molecules
Heiner Saßmannshausen, Frédéric Merkt, Johannes Deiglmayr
We observe the formation of long-range Cs Rydberg molecules consisting of a Rydberg and a ground-state atom by photoassociation spectroscopy in an ultracold Cs gas near 6s$_{1/…
Observation of dipole-quadrupole interaction in an ultracold gas of Rydberg atoms
Johannes Deiglmayr, Heiner Saßmannshausen, Pierre Pillet +1
We observe the direct excitation of pairs of Cs atoms from the ground state to molecular states correlating asymptotically to asymptotes. The molecular resonances are int…
Manipulating Rydberg atoms close to surfaces at cryogenic temperatures
Tobias Thiele, Stefan Filipp, Josef Anton Agner +6
Helium atoms in Rydberg states have been manipulated coherently with microwave radiation pulses near a gold surface and near a superconducting NbTiN surface at a temperature of $3…
