lifetime damping [1], energy renormalization [2] and topological phase transitions [3] that arise purely due to magnon-magnon interactions and can alter the flow of magnons dramatically. In this work we primarily investigate the results of three and four magnon interactions in the topologically non-trivial collinear honeycomb antiferromagnet and the results of these interactions in the magnon Spin Nernst effect. If time allows the impact of magnon interactions in a noncollinear antiferromagnet will also be addressed.
