Coexisting Regular and Chaotic Dynamics in the Dysprosium Feshbach Spectrum
Julie Veschambre, Alexandre Journeaux, Maxime Lecomte +7
Strongly dipolar gases, such as dysprosium, erbium and thulium, exhibit dense Feshbach spectra whose level statistics have been associated with quantum chaos arising from couplings…
Determination of the ground state polarizability of Dy near 530 nm
Alexandre Journeaux, Maxime Lecomte, Julie Veschambre +3
Open-shell lanthanide atoms, and dysprosium in particular, combine a large ground-state angular momentum with dense electronic spectra, making their dynamical polarizability strong…
A two-dimensional realization of the parity anomaly
Nehal Mittal, Tristan Villain, Mathis Demouchy +4
Quantum anomalies arise when symmetries of a classical theory cannot be preserved upon quantization, leading to unconventional topological responses. A prominent example is the par…
Two-Body Contact Dynamics in a Bose Gas near a Fano-Feshbach Resonance
Alexandre Journeaux, Julie Veschambre, Maxime Lecomte +5
We investigate the real-time buildup of short-range correlations in a nondegenerate ultracold Bose gas near a narrow Fano-Feshbach resonance. Using rapid optical control, we quench…
Production and stabilization of a spin mixture of ultracold dipolar Bose gases
Maxime Lecomte, Alexandre Journeaux, Julie Veschambre +2
Mixtures of ultracold gases with long-range interactions are expected to open new avenues in the study of quantum matter. Natural candidates for this research are spin mixtures of…
Dynamics of spatial phase coherence in a dissipative Bose-Hubbard atomic system
Rémy Vatré, Raphaël Bouganne, Manel Bosch Aguilera +4
We investigate the loss of spatial coherence of one-dimensional bosonic gases in optical lattices illuminated by a near-resonant excitation laser. Because the atoms recoil in a ran…
