Exploring nonadiabatic effects in Rydberg molecules

Long-range Rydberg molecules are bound states that occur because of interactions between Rydberg atoms with ground-state atoms, ions or other Rydberg atoms. Such molecules offer insights into ultracold chemistry, few-body dynamics and scattering processes. Recently various types of Rydberg molecules have been suggested to study nonadiabatic effects. Here we study nonadiabatic mixing between 85Rb 33PJ and 5S1/2 atoms, which exhibit a resonance between their respective fine structure and hyperfine structure energies. The poster presents an overview of developments in the field of Rydberg physics, including the origins of these effects, their influence on molecular spectra, molecular stability, and progress towards probing them experimentally. Additionally, using an intra-cavity near-concentric resonator, we investigate adiabatic potentials of coherently mixed hydrogenic states in deep ponderomotive optical lattices.
