Probing spin dynamics from the Mott insulating to the superfluid regime in a dipolar lattice gas
journal contribution
posted on 2023-06-09, 12:02 authored by A de Paz, P Pedri, A Sharma, M Efremov, B Naylor, O Gorceix, E Maréchal, L Vernac, B Laburthe-TolraWe analyze the spin dynamics of an out-of-equilibrium large spin dipolar atomic Bose gas in an optical lattice. We observe a smooth crossover from a complex oscillatory behavior to an exponential behavior throughout the Mott-to-superfluid transition. While both of these regimes are well described by our theoretical models, we provide data in the intermediate regime where dipolar interactions, contact interactions, and superexchange mechanisms compete. In this strongly correlated regime, spin dynamics and transport are coupled, which challenges theoretical models for quantum magnetism.
