12.05.2026 The RING project in Germany: 1 Postdoc and 14 PhD positions in Physics, Geophysics, Geodesy we would like to draw your attention to the 4-year RING project recently funded by the German Research Foundation (extendable to 8 years). The project has strong overlap with gravitational wave detection research on instrumentation. The project aims at pushing the sensitivity and stability limits of rotational motion sensing with ring laser technology into new realms using approaches from quantum optics and metrology. The ultimate goal is to enable ring laser observations as a complement to classic space-geodetic methods towards more precise, high-rate estimation of Earth Orientation Parameters (EOP). Furthermore, we plan to develop…
