Diffusion transitions induced by shear-thinning viscosity: application to laser-cooled atomic gases

We study the diffusive dynamics of a system in a nonlinear velocity-dependent frictional environment within a continuous time random walk model. In this model, the motion is governed by a shear-thinning frictional force, $-\gamma_0v/[1+(v^2/v_{\mathrm{c}}^2)]^\mu$ ( $0\lt\mu\unicode{x2A7D}1$ ), wher...
