The assembly of the new vacuum chamber begins
After a long design period, we have just started the construction of the main vacuum chamber for version 2.0 of the chromium BEC experiment. The assembly is powered by our new post-doc Fatima and our summer intern Esther. Let’s hope there is no leak!
New paper out!
Our new paper Using dynamical decoupling to investigate magnetism of large-spin atoms from the chromium BEC lab is out. You can find it on the website Phys. Rev. A at this link.
New arrival: Esther Fromm
A warm welcome to Esther Fromm, the new member of the chromium BEC lab team.
New paper in Phys. Rev. Lett.
Our paper Probing coherences and itinerant magnetism has just been published in Physical Review Letters. You can find it at this link or on arXiv.
Using dynamical decoupling to investigate magnetism of large-spin atoms
In the low-entropy, near-unit filling regime, we employ advanced dynamical decoupling techniques to suppress magnetic-field noise and probe spin coherence across the superfluid–Mott insulator transition. Phys. Rev. A 113, 033306 (2026)

QuRIOUS doctoral network
We celebrate the success of the Qurious doctoral training network: we now have partners all across Europe, with whom to develop a new generation of atomic clocks and train 15 PhDs. More informations on the network at https://www.quriousclocks.eu/ and on thesis opportunity in our group here.
The atomic beam crosses the cavity mode.
The preparation of the atoms in the excited state, before they enter the cavity, seems to work. Efforts are under way to laser-cool further the atomic velocity distribution, in directions transverse to the atomic beam flow.
