TL;DR: Atomistic simulations indicate that the fluctuation state largely reduces the topological energy barrier and thereby enables the observed rapid and homogeneous nucleation of the skyrmion phase, and suggest a path towards ultrafast topological switching in a wide variety of materials through intermediate fluctuating states.
