Active rheology in odd-viscosity systems

Abstract Odd viscosity arises in systems with time reversal symmetry breaking, which creates non-dissipative effects. One method to probe changes is examine the dynamics of a single particle driven though medium, technique known as active rheology. We show that rheology system odd and no quenched disorder reveals variety novel effects, including speed up increasing density when background medium velocity boost due Magnus effect. In contrast, dissipation-dominated limit monotonically decreases density. also imparts Hall angle particle, both depend strongly on drive. These results should be general other viscosity, skyrmions chiral magnets.
