November 2022: The green ytterbium MOT
For unconventional problems, look for unconventional solutions.
The fiber lab uses a dentist drill for drilling in tiny things.
The rubidium experiment is shiny! But the backstory is sad. Due to a broken ion detector the vacuum had to be opened for a greater operation. This is the new ion detector. We have high hopes for this one!
The group in May 2022

December 2020: Beautiful sunrise over Bonn and moving trucks with the ytterbium experiment. This will be the new home!
Dancing with physicists! The new labs in Bonn are getting ready!
Extreme supervision of master student!
We are pretty crucial to the functionality of the department of Physics, Chemistry and Pharmacy in Odense! Coffee machine not broken anymore ☕ The chemists can thank us later.
Plan for new labs. Life is sweet in Gummy Bear Lab.
Outdoor stuff is allowed again! 🍧🌞😎 Part of NQO group going for ice cream in nice weather. Hannes takes the picture.
University is all empty during lockdown. Only essential workers allowed. Hannes is essential ♥

Advanced experiment-theory collaboration!
We have experimentally observed correlations between three photons! Here the observed connected third order correlation function in Jacobi coordinates!
A photo from the empty lab before the new ceiling was put in. The wrapped experiment has been decorated with a bow, and we look forward to unpacking it!
The group in February 2018.
We have successfully measured the first EIT signal in our new lab in Odense. We still have to optimize the signal a bit and especially start to optically pump our atoms. But this is already a good start.
We successfully captured the first Rubidium atoms after the move to Odense and can already load them into the optical dipole trap. Next we will align the probes.
During the night, the fluoresence of the magneto-optical trap is much brighter?
