  Many emergent phases of matter stem from the intertwined dynamics of
quasiparticles. Here we show that a topological superconducting phase emerges
as the result of interactions between electrons and magnons in a quantum wire
and a helical magnet. The magnon-mediated interaction favors triplet
superconductivity over a large magnetic phase space region, and stabilizes
topological superconductivity over an extended region of chemical potentials.
The superconducting gap depends exponentially on the spin-electron coupling,
allowing it to be enhanced through material engineering techniques.
