Query: Unified formulation of interfacial magnonic pumping from non-collinear
  magnets   We establish a general formulation for spin current pumped by magnons at the
interface between a normal metal and a magnetic insulator, valid for any
non-collinear magnetic configuration in the linear spin wave regime. This
current is generated by driving the system in a non-equilibrium state, covering
setups such as thermal spin injection (spin Seebeck effect) or spin voltage by
irradiation of the insulator (spin pumping). We illustrate the formula in the
special case of a honeycomb topological ferromagnet, for simplicity, and cover
both the spin Seebeck and spin-pumping setups. We show how the topological
parameters influence the spin current and propose a way to obtain a
contribution mainly from the topological edge magnons in the spin pumping case.
