The RING project in Germany: 1 Postdoc and 14 PhD positions


Dear colleagues,

We would like to draw your attention to the 4-year RING project recently
funded by the German Research Foundation (extendable to 8 years).

Successful candidates will have the opportunity to join a vibrant,
multidisciplinary team formed by 14 PhD students, one postdoc, the lead
and associate scientists tackling various science questions in the
unique environment of the RING research unit in the fields of
laser physics, geodesy, geophysics, hydrology, and seismology. 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 techniques towards more precise, high-rate estimation of Earth
Orientation Parameters (EOP). This will lead to a better understanding
what affects polar motion and length-of-day variations on small time
scales. Furthermore, we plan to develop (trans-) portable ring lasers
fit for weak, broadband 6 degree-of-freedom ground motion observations
towards better understanding of atmosphere-solid Earth coupling (also
relevant for seismic decoupling of gravitational wave detection
facilities).

More information, links to the individual research projects and open
positions can be found here:

We would ask you to forward this information to potential candidates,
PhD/MSc student mailing (or other relevant) lists at your institutions.

Thank you very much!

Best regards,

Susanne Glaser
on behalf of the RING consortium with Heiner Igel as Spokesperson
