Short-Range Photoassociation and Trilobite-Like States of Ultracold Rb2

Michael Bellos

I demonstrate the formation of rubidium dimers via photoassociation and spontaneous emission at short internuclear distances. This short-range photoassociation allows the formation of deeply bound molecules, including, for instance, the lowest rovibrational level of the lowest triplet state: a(0,0). This particular state is interesting because it is metastable against radiative decay, and possibly long-lived in optical and/or magnetic traps. In a second experiment, I demonstrate the population of trilobite-like excited states of Rb2. Trilobite-like states are bound by an unusual chemical bond, and can have large physical dimensions and electric dipole moments. I demonstrate the population of these states through the ultraviolet excitation of weakly bound molecules. By using the same ultraviolet excitation scheme, I place a new upper-bound on the minimum energy required to ionize 85Rb2 molecules.I demonstrate the formation of rubidium dimers via photoassociation and spontaneous emission at short internuclear distances.

Production of trilobite Rydberg molecule dimers with kilo-Debye permanent electric dipole moments

Donald W. Booth, Seth T. Rittenhouse, J. Yang +2 more

Permanent electric dipole moments are important for understanding symmetry breaking in molecular physics, control of chemical reactions, and realization of strongly correlated many-body quantum systems. However, large molecular permanent electric dipole moments are challenging to realize experimentally. We report the observation of ultralong-range Rydberg molecules with bond lengths of ~100 nanometers and kilo-Debye permanent electric dipole moments that form when an ultracold ground-state cesium (Cs) atom becomes bound within the electronic cloud of an extended Cs electronic orbit. The electronic character of this hybrid class of "trilobite" molecules is dominated by degenerate Rydberg manifolds, making them difficult to produce by conventional photoassociation. We used detailed coupled-channel calculations to reproduce their properties quantitatively. Our findings may lead to progress in ultracold chemistry and strongly correlated many-body physics.Permanent electric dipole moments are important for understanding symmetry breaking in molecular physics, control of chemical reactions, and realization of strongly correlated many-body quantum systems.
