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.
Coherent control over the high-dimensional space of the nuclear spin of alkaline-earth atoms
We demonstrate coherent manipulation of the nuclear degrees of freedom of ultracold ground-state strontium-87 atoms, thus providing a toolkit for fully exploiting the corresponding large Hilbert space as a quantum resource and for quantum simulation experiments with 𝔰u(𝑁)-symmetric matter.
