- Abstract summary: We probe a single atomic ion excited to Rydberg states and confined in the electric fields of a Paul trap.
The quadrupolar trapping fields cause atomic energy level shifts and give rise to spectral sidebands.

- Abstract: 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 electric quadrupole field to second- and higher
orders; this arises from the atom's electric quadrupole polarizability and
hyperpolarizabilities. We probe a single atomic ion which is excited to Rydberg
states and confined in the electric fields of a Paul trap. The quadrupolar
trapping fields cause atomic energy level shifts and give rise to spectral
sidebands. The observed effects are described well by theory calculations.

Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems.
We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

We show that the effect of the plate is to increase the probability of emission when the atom is near the plate and oscillates along a direction perpendicular to it.

Recent demonstrations of electric-field (E-field) sensitivities in molecular spin materials are tantalising.
E-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin-electric couplings.
