Observing the Bloch oscillations of an ultracold quantum gas in an optical lattice is a promising approach to measure weak forces with high precision. The creation time of these ultracold quantum gas in combination with the common detection via Time-of-Flight imaging inherit a bad data acquisition speed.
In our Recent work [1] we have shown experimentally, the direct observation of Bloch oscillation of a strong cooperative coupled BEC inside an optical cavity via the light leaking out of this cavity. And in this way, we accelerated the acquisition speed for the Bloch-frequency substantially.
Here we report on our newest results on open questions concerning this detection scheme. Among others, we investigated the question if our coupling scheme changes the Bloch-frequency.
