Abstract
Rydberg states are extremely sensitive to electric fields. In the seminal theoretical investigation by Müller et al. [1] effects of strong electric trapping fields on highly-sensitive Rydberg ions were predicted. Experimental observation of these effects is presented here. In this chapter we also investigate a Rydberg ion in trapping regimes beyond the consideration of Müller et al.; both theoretically and experimentally.

Notes
- 1.
Generally \(\omega _x\ne \omega _y\) and \(\epsilon \ne 0\) and thus \(\vec {\mathrm {r}}_{\mathrm {rf}}\), \(\vec {\mathrm {r}}_{\mathrm {dc}}\) and \(\vec {\mathrm {r}}_{\mathrm {g}}\) are not collinear.
- 2.
Since the Rydberg-excitation lasers counter-propagate (Sect. 4.4), the contribution to phonon-number-changing transitions described by the Lamb–Dicke parameter is small compared with the Franck–Condon factors considered in this section.
- 3.
The linear relation holds for one radial direction provided that the ion is close to the trap centre in the orthogonal radial direction.
