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...

For their outstanding dissertations in quantum optics, Giorgio Zarantonello and Peter Micke receive the Wilhelm & Else Heraeus Young Physicists Award. For this prestigeous award and the amazing achievement we congratulate them.

Till Rehmert joins the molecular ion quantum logic spectroscopy team as a PhD student. He previsously already did his masters degree with us and recieved his bachelor's degree from Leibniz University of Hannover.

Till Rehmert receives his Master's degree. We congratulate him on this achievement.

The topic of his thesis is:

'VECSEL system for coherent manipulation of trapped magnesium ions'

The Quantum logic spectroscopy group has succesfully applied for joint funding together with Roee Ozeri's trapped ions lab at the Weizmann Institute of Science, where we will use tailored quantum states to improve performance of optical clocks.

We have trapped the first ca ions in our new macroscopic blade trap. The ions were loaded  by laser ablation from a calcium target and subsequent multiphoton ionization.

The picture shows our new trap outside the vacuum chambre. The inset shows  the first ion crystal loaded in the trap and imaged...

The Aluminum-quantum-logic team has recently observed coherent excitation of the logic transition in a single trapped Aluminum-ion. Now also coherent excitation of the clock transition was achieved. A scan of the clock transition is shown in the picture with a linewidth of 43Hz (FWHM) for a gaussian...

Alexander Wilzewski joins the Highly Charged Ions team as a PhD student. Previously he received a Bachelor's and Master's degree from Johannes Gutenberg University at Mainz, and joined a US exchange program in 2017. We welcome him to the group!

The Sonderforschungsbereich Designed Quantum States of Matter (DQ-mat) has been renewed for another funding period of four years. For mor details see the news-article at the webpage of the SFB.

Peter Micke succesfully defends his Ph. D. thesis. We congratulate him on this achievement.

The topic of his thesis is:

‘Quantum Logic Spectroscopy of Highly Charged Ions’
