Impact of micromotion and field-axis misalignment on the excitation of Rydberg states of ions in a Paul trap
Wilson S. Martins, Joseph W. P. Wilkinson, Markus Hennrich +1
Trapped ions are among the most advanced platforms for quantum simulation and computation. Their capabilities can be further augmented by making use of electronically highly excite…
Exploring the many-body dynamics near a conical intersection with trapped Rydberg ions
Filippo Maria Gambetta, Chi Zhang, Markus Hennrich +2
Conical intersections between electronic potential energy surfaces are paradigmatic for the study of non-adiabatic processes in the excited states of large molecules. However, sinc…
Magic trapping of a Rydberg ion with a diminished static polarizability
Fabian Pokorny, Chi Zhang, Gerard Higgins +1
Highly excited Rydberg states are usually extremely polarizable and exceedingly sensitive to electric fields. Because of this Rydberg ions confined in electric fields have state-de…
Observation of effects due to an atom's electric quadrupole polarizability
Gerard Higgins, Chi Zhang, Fabian Pokorny +4
The response of matter to fields underlies the physical sciences, from particle physics to astrophysics, and from chemistry to biophysics. We observe an atom's response to an elect…
Interferometric thermometry of a single sub-Doppler cooled atom
L. Slodička, G. Hétet, N. Röck +5
Efficient self-interference of single-photons emitted by a sideband-cooled Barium ion is demonstrated. First, the technical tools for performing efficient coupling to the quadrupol…
