The quantum logic spectroscopy group is currently looking for several Masters-students for masters-thesis-projects.

Projects at the Aluminum-quantum-logic-spectroscopy group, with focus on frequency stabilization of lasers using optical resonators. Link to flyer.

Projects at the Multi-Ion Calcium...

Atomic clocks operate at extraordinary levels of precision and accuracy, and can be used for searches for new physics beyond the Standard Model of particle physics (SM) by searching for miniscule deviations in their operating frequencies. For example, a hypothetical fifth force between the neutrons...

Our group has secured an ERC Advanced grant to investigate highly-charged ions as optical clocks and for tests of fundamental physics using quantum logic spectroscopy. For more details refer to link.

Especially with such major funding opportunities we are now more than ever looking to fill PhD and...

We investigate the temperature dependence of the low-frequency vibrational spectrum of an ion Coulomb crystal near the linear to zigzag transition. For zero temperature, the linear to zigzag transition is a second-order phase transition that exhibits, amongst other things, a soft mode, which is a...

Bloomberg Quickshot released a new video about time dilation and clocks on Youtube featuring interviews with Don Lincoln (Fermi Lab), David Hume (NIST) and Tanja Mehlstäubler (PTB/LUH). Very cool!
