We investigate the intensity stability of a superradiant laser in the configuration where a continuous beam of atoms in an electronically excited state crosses the mode of a high-finesse Fabry-Perot cavity. We show that such superradiant laser can become unstable and develop chaotic behavior.

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)
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.

We report on the study of itinerant magnetism of lattice-trapped magnetic atoms, driven by magnetic dipole-dipole interactions, in the low-entropy and close-to-unit filling regime.

We demonstrate a bipartition technique using a superlattice architecture to access correlations between alternating planes of a mesoscopic array of spin-3 chromium atoms trapped in a 3D optical lattice.

We study whether a generic isolated quantum system initially set out of equilibrium can be considered as localized close to its initial state. Our approach considers the time evolution in the Krylov basis, which maps the dynamics onto that of a particle moving in a one-dimensional lattice where both the energy in the lattice sites and the tunneling from one lattice site to the next are inhomogeneous.

We propose a minimalistic model to account for the main properties of a continuous superradiant laser, in which a beam of atoms crosses the mode of a high-finesse Fabry-Perot cavity, and collectively emits light into the cavity mode.

We perform collective spin measurements to study the buildup of two-body correlations between ≈10^4 spin s=3 chromium atoms pinned in a 3D optical lattice.

In this review, we aim to present the aspects of the magnetic quantum-gas platform that make it unique for exploring ultracold and quantum physics as well as to give a thorough overview of experimental achievements.
