scales. Ultracold gases provide fertile platforms to explore this phenomenon, due to the
involvement of a wide range of length scales ranging from short ones e.g. the healing
length determined by the s-wave interactions to macroscopic scales set by external traps.
Gases with long-range interactions, such as magnetic dipoles, may further aid in
unveiling the universal characteristics of quantum turbulence due to the existence of
competing interactions. We unravel the emergent energy cascade in quasi-two-
dimensional dipolar gases within the extended Gross-Pitaevskii framework. To initiate
such a cascade, the system is periodically driven across the superfluid to supersolid
transition and vice versa. A power-law decay is observed in the long-wavelength limit of
the energy density spectrum and the momentum distribution. The exponent of such a
decay is investigated for different initial states and characteristics of the driving
protocol, revealing signatures of wave quantum turbulence.
