Observation of Rydberg-atom macrodimers: micrometer-sized diatomic molecules
Heiner Saßmannshausen, Johannes Deiglmayr
Long-range metastable molecules consisting of two cesium atoms in high Rydberg states have been observed in an ultracold gas. A sequential three-photon two-color photoassociation s…
Long-range Rydberg molecules, Rydberg macrodimers and Rydberg aggregates in an ultracold Cs gas
Heiner Saßmannshausen, Johannes Deiglmayr, Frédéric Merkt
We present an overview of our recent investigations of long-range interactions in an ultracold Cs Rydberg gas. These interactions are studied by high-resolution photoassociation sp…
Precision measurement of the ionization energy of Cs I
Johannes Deiglmayr, Holger Herburger, Heiner Saßmannshausen +3
We present absolute-frequency measurements for the transitions from the 6s ground state of Cs to p and p Rydberg states. The transition freque…
Pulsed excitation of Rydberg-atom-pair states in an ultracold Cs gas
Heiner Saßmannshausen, Frédéric Merkt, Johannes Deiglmayr
Pulsed laser excitation of a dense ultracold Cs vapor has been used to study the pairwise interactions between Cs atoms excited to p Rydberg states of principal quantum…
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…
