Motion of micron-size particles in turbulent helium II

The surprising result of a recent experiment in turbulent helium II is that micron-size tracer particles move with about half the speed of the imposed normal fluid. We develop a theory of the interaction of small spheres with quantized vortices and predict that the particles' slip velocity (res...
