Scientists Discover Spin Polarization Induced by Shear Flow

Chinese researchers recently discovered a new effect that can generate spin-polarization in fluid. The new effect, which is called "shear-induced polarization (SIP)", predicts that shear flow can induce polarization in the momentum space. Figure 1. left: the polarization induced by the vortical flow; right: the polarization induced by the shear flow. Red and yellow arrows represent the spin and momentum directions respectively.
