Texture-induced spin-orbit coupling and skyrmion-electron bound states in a Néel antiferromagnet
Résumé
We show that, in a N\'eel antiferromagnet with a particular location of electron band extrema, a Skyrmion and an electron form bound states with energy of the order of the gap $\Delta$ in the electron spectrum. The bound states turn the Skyrmion into a charged particle, that can be manipulated by electric field.
