Pulse area dependence of multiple quantum coherence signals in dilute thermal gases
Benedikt Ames, Andreas Buchleitner, Edoardo G. Carnio +1
In the general framework of open quantum systems, we assess the impact of the pulse area on single and double quantum coherence (1QC and 2QC) signals extracted from fluorescence em…

Probing surface charge densities on optical fibers with a trapped ion
Florian R. Ong, Klemens Schüppert, Pierre Jobez +8
We describe a novel method to measure the surface charge densities on optical fibers placed in the vicinity of a trapped ion, where the ion itself acts as the probe. Surface charge…

Observation of superconductivity and surface noise using a single trapped ion as a field probe
K. Lakhmanskiy, P. C. Holz, D. Schärtl +5
Measuring and understanding electric field noise from bulk material and surfaces is important for many areas of physics. In this work, we introduce a method to detect in situ diffe…
