5) Abstract
- Parity-breaking hydrodynamics predicts a universal dissipationless transport coefficient called Hall viscosity, which has been extensively studied in various interesting systems. For example, in quantum Hall systems, it has been related to half of angular momentum or momentum-dependent part of Hall conductivity depending on symmetries. We introduce Hall viscosity to skyrmion systems by generalizing Ward identity with topological charges. We also provide possible ways to verify its existence by contrasting skyrmion and antiskyrmion Hall angles. In this talk, we will discuss Hall viscosity and its properties related to various topological phenomena.
