Abstract:
Triplet superconductivity arises in systems where the effective electronic attraction favors Cooper pairs with a symmetric spin structure, as may occur in non-collinear magnetic systems. Here we show that topological triplet superconductivity can be realized in a one-dimensional quantum wire through the interaction with magnetic fluctuations of a helical magnet. The magnon-mediated attraction favors triplet superconductivity over a large sector of magnetic parameters, and stabilizes a topological phase with a superconducting gap of the order of 1 meV over an extended region of chemical potentials.
