Hall viscosity at angular momentum compensation point

Symmetries have served as an overarching theme to investigate interesting physical systems by connecting theoretical tools to experimental results. Chiral magnetic Skyrmions exist in materials without mirror (parity) symmetry. Hydrodynamic approaches, when parity symmetry is broken, uncover Hall viscosity, a universal and dissipationless transport coefficient. Previously we examined existing data to reveal that the Hall viscosity amounts 3\% - 5.4\% of skyrmion Hall effect by modeling Hall viscosity with a transverse velocity component of Thiele equation. This Hall viscosity plays role even in anti-ferromagnetic systems without skyrmion Hall effect. Here we propose different ways to reveal Hall viscosity in the angular momentum compensation point.
