제목: Skyrmion charge, Ward identity and Hall transport.

초록: Ward identity is a powerful tool that relates various
physical quantities based on symmetries and plays important roles in
systems with broken parity in recent years. We generalize the Ward
identity to capture the effects of centrally extended topological
charge, such as Skyrmions. The charge density turns out to be
proportional to thermal Hall conductivity in the electrically neutral
case. In charged case, the electric Hall conductivity has a distinct
signature from the topological charge, which we identify with existing
experimental data. We further provide various implications in Skyrmion
experiments.
