Description
The non-equilibrium turbulent response of periodically driven three-dimensional ultracold dipolar gases is induced by an external time-dependent ring potential. To model this system and monitor its non-equilibrium quantum dynamics, we invoke an extended Gross-Pitaevskii framework containing the first-order quantum correction to the mean-field energy functional. The shape of the external perturbing potential is chosen to trigger angular roton excitations, driving the supersolid configuration out of equilibrium and attaining a turbulent state. Following the generation of shallow vortical defects in the bulk, a direct cascade front manifests, transporting energy from larger to smaller length scales. This leads to a non-equilibrium quasi-steady state at long evolution times. This state is identified by the self-similar character of the momentum distributions exhibiting an algebraic reduction at large momenta with scaling exponents supporting wave turbulence. Our simulations reveal turbulent and self-similar behavior in anisotropically interacting magnetic quantum gases.

Direct Energy Cascade of 2D Quantum Turbulence in Supersolids
