Measuring electric fields from surface contaminants with neutral atoms
In this paper we demonstrate a technique of utilizing magnetically trapped neutral $^{87}\mathrm{Rb}$ atoms to measure the magnitude and direction of stray electric fields emanating from surface contaminants. We apply an alternating external electric field that adds to (or subtracts from) the stray field in such a way as to …
