Abstract:

Theory and simulations establish the effects of shear on the collisional diffusion of a 2D point vortex gas. For finite shear, the diffusion is considerably smaller than previous zero-shear theories predict, scaling inversely with the shear. Surprisingly, changing the sign of the applied shear changes the diffusion by an order of magnitude.
