Spatial calibration of high-density absorption imaging
Toke Vibel, Mikkel Berg Christensen, Mick Althoff Kristensen +4
The accurate determination of atom numbers is an ubiquitous problem in the field of ultracold atoms. For modest atom numbers, absolute calibration techniques are available, however…

Sub-atom shot noise Faraday imaging of ultracold atom clouds
Mick A. Kristensen, Miroslav Gajdacz, Poul L. Pedersen +4
We demonstrate that a dispersive imaging technique based on the Faraday effect can measure the atom number in a large, ultracold atom cloud with a precision below the atom shot noi…
