Query: Magnon spin transport around the compensation magnetic field in
  easy-plane antiferromagnetic insulators   In this work, we theoretically study the magnon spin transport in easy-plane
antiferromagnetic insulators in the presence of an in-plane magnetic field. By
exactly calculating the magnon spectrum, we find the band splitting due to the
magnetic anisotropy can be fully compensated by the external field at a
particular strength, which makes its dynamics nearly equivalent to an easy-axis
antiferromagnet. As a result, the intrinsic magnon spin Hall effect due to the
dipole-dipole interaction, previously predicted in easy-axis antiferromagnets
is activated in easy-plane antiferromagnets. The compensation feature also
allows the field control of magnon spin lifetime and hence the spin diffusion
length. The compensation feature is robust against the biaxial anisotropy.
