Zusammenfassung: | The nonequilibrium turbulent response of driven three-dimensional dipolar
gases is monitored by dynamically crossing the supersolid-to-superfluid phase
transition and vice versa utilizing a periodically modulated scattering length.
Following the generation of vortical defects in the bulk, a direct cascade
front emerges transporting energy from larger to smaller length scales and
leading to a nonequilibrium quasi-steady state at long evolution times. This
quasi-steady state is evidenced by the self-similar character of the momentum
distributions featuring an algebraic reduction at large momenta with scaling
exponents supporting the existence of wave turbulence. We observe that
supersolidity sustaining higher-lying momenta, associated with the roton
minimum, promotes the emergence of turbulence. Our results provide a stepping
stone for unravelling and exploiting turbulent and self-similar behavior in
anisotropically interacting quantum gases amenable in current experiments. |
