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\u2013Mott insulator transition. Phys. Rev. A 113, 033306 (2026) <\/a><\/div>\n\n\n

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 \ud835\udd30u(\ud835\udc41)-symmetric matter. \narXiv:2501.01731 (2025)<\/a> \/ PRX Quantum 6, 020352 (2025)<\/a><\/div>\n\n\n

In this paper, we present a systematic derivation of the effective Hamiltonian for the nuclear spin states of ultracold fermionic atoms due to such an off-resonance light. We obtain compact expressions for the scalar, vector, and tensor light shifts taking into account both linear and quadratic contributions to the hyperfine splitting.\narXiv:2404.12429 (2024)<\/a> \/ Phys.

Bruno Laburthe-Tolra<\/a>,\u00a0Youssef Aziz Alaoui<\/a><\/div>\n\n
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.\narXiv:2307.10706 (2023)<\/a> \/ Phys.

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.\narXiv:2210.05464 (2022)<\/a> \/ SciPost Phys.

Spontaneous symmetry breaking is a property of Hamiltonian equilibrium states which, in the thermodynamic limit, retain a finite average value of an order parameter even after a field coupled to it is adiabatically turned off. In the case of quantum spin models with continuous symmetry, we show that this adiabatic process is also accompanied by the suppression of the fluctuations of the symmetry generator\u2014namely, the collective spin component along an axis of symmetry.\narXiv:2202.08607 (2022)<\/a> \/ Phys.
