Rayleigh-Taylor instability occurs at the interface of two fluids with different density in presence of an acceleration. RT instability, and its nonlinear evolution into fully developed turbulence, are ubiquitous mixing phenomena occurring in many natural systems and in technological applications.

RT instability is affected by the presence of many physical ingredients, including compressibility, surface tension, viscoelasticity and rotation. In this talk, I will show how two well known linearly stabilizing mechanisms, rotation and vibration, produce a slow-down and eventually arrest the evolution of the turbulent mixing layer.
