We formulate a theoretical description of antiferromagnetic magnons and their transport in terms of an associated pseudospin. The need and strength of this formulation emerges from the antiferromagnetic eigenmodes being formed from superpositions of spin-up and -down magnons, depending on the material anisotropies. Consequently, a description analogous to that of spin-$\frac{1}{2}$ electrons is demonstrated while accounting for the bosonic nature of the antiferromagnetic eigenmodes. Introducing… Expand
