Skyrmion v.s. antiskyrmion Hall angles and Hall viscosity

ORAL

Abstract

Hall viscosity has been much studied theoretically in quantum Hall systems. We demonstrated, using quantum field theory Ward identities, that this Hall viscosity is also a part of universal transport coefficients in skyrmion motion. Here we advertise that Hall viscosity has a better chance to be verified through the difference between the skyrmion and antiskyrmion Hall angles, which is about 10% according to the available experimental data sets.
